So I go to our Wednesday night get together, and back in to a parking spot.  Then when I went to put it in first gear to shut down, the shifter just went all the way forward to the edge of the console opening and no gear.  Could move the shifter all the way around the console opening.  No H pattern.  Then when I pulled it all the way back on the left side, I got second gear, but the shift lever is all the way back against the console opening.
Was able to drive home in second gear.
Pushing forward on the lever gets nothing.  No first, third or reverse.
I guess something came apart.
So, I know I can get to where the rods connect with the transmission from underneath, how much can I get to from the top?
Will jack it up tomorrow and start the investigation.
It's always something!  Thumbs Down

Thoughts?

Well, I can tell you this, from experience. Getting to the shifter and removing it will be a REAL problem. Sounds to me like if it's never been out and is original, it'll have to come out. Corvette America supplied mine. Check where the rod ends bolt to the transmission to see if one is loose or came off. Also check to see if the clips on the rod ends are worn through and fell off. Hopefully you won't have to pull the mount out and shifter. 😡 🔨🔧 Won't be fun! Keep us updated.

OK, here is what I found.  The bolt that goes thru the shifter and bolts it to the the mount is loose.  Does it tighten in to a threaded piece, or does it have a nut on the end.  Seems like it does not have a nut.  Can I put a nut on it as I think the threading is stripped.  Won't tighten up. 
Will the mount come out without the shifter?
Can I get the bolt out without the whole mechanism falling apart?
Am I screwed?

OK, I got the mounting bracket out!  Yay.  Now, once I get the bracket fixed i.e. weld on a nut, I'm not sure I can get it all back together.  The shifter is still in the car, and the exhaust pipes are still there.  How do you bolt the shifter back on to the bracket?  Seems that lower, smaller bolt is impossible to get to to start and then tighten up.

You are correct on All points. Shifter is a pain and the site is going down hill. I had to lower the pipes, and remove the shifter to deal with mine. Not much room to work in there, and would be best to have another person to help from inside the car. They can see where you can't and can help line things up. Hope you have a lift. so much easier to set on a creaper rather than on your back.

Thanks for responding Manchester.  Thought for sure Joel would chime in, hope he is OK.  My membership runs out in January, and I'm not sure I'll renew.

So I got everything out and I welded a nut on both bolt holes on the bracket.  May as well beef them both up.  I just have to remember how it all came out and reverse the order.

Kinda like a chinese puzzle.  Plus I have to remember which bolts go where.

Stick with it my friend. These cars are a work of love. They may have difficulties, BUT well worth it. As for the site, stay here. It is a good place to get information and assistance. It may take time, but it ALWAYS has the answer to some problem we face. If you opt out, that's just one more hole in the forum. Take your time, be patient and all will fall into place with the shifter. There are books with pictures and internet videos to show "How To". Joel is still in there, just may not be familiar with your dilemma. He can post pictures, I'm not that good with this letric wizard.

Gary, congrats on getting the bracket out for repair, was the welded on nut stripped out or did the welds break allowing the nut to come loose ?? I have to admit Iíve never heard of that one either way. As you already know getting it back in is more than challenging. A couple years ago I repaired a worn out shifter for a friend with a 69 BB. Same as you, I removed the bracket then the shifter. I got access to the main bolt and the smaller lower bolt from the top end by removing the console plate and the lower rubber boot. Main bolt not so bad, the small bottom one a major trial on your patience. If you have to disconnect the shift rods to get addition clearance/movement disconnect for rods from the trans NOT the shifter. Good luck and I hopes this helps out !!

Yea, that lower bolt is a female dog.
So I had nuts welded to both bolt holes.  The upper was completely stripped and the lower looked pretty worn.
Got the shifter mounted to the bracket and have everything bolted up except the for the transmission crossmember.
Now I can't move the shift lever at all.  Not for and aft, and not left and right.  Am I stuck in a gear?
the front shift lever on the tranny it straight up, the aft lever is pushed forward, so I guess I am in a gear.  But I push in the clutch and the lever will not shift any gears.
That is with the reverse rod connected or not.
?????
Should I get under there, disconnect the shift rods from the tranny and move one or both of the shift levers on the tranny?
Or should I let it down off the jacks, start it up and see if by moving the car a little bit, it will shift?

Does anyone know where the shift levers should be in neutral?

The levers on the transmission MUST be in neutral as well as the shifter before you attach the shift rods. If you get them out of sync you have another problem. A tool can be made to keep the shifter in neutral while you have the trans in neutral in all gears. THAT my friend is the female dog to accomplish. I made one that worked well, but it was a royal pain to insert. Hope you only have to do this job once. take a large break before attempting it twice.

Gary, the two main trans levers on the side of the case should be straight up for neutral. The reverse lever, which is the one I hope is causing you issue should be in its forward position. Sorry I donít remember which way the lever points for that one. I say hope because what you describing happened to me on my car, all hooked up and stuck. After a few choice words I realized I had bumped the reverse lever when I hooked up the reverse rod and it was in gear and neither of the other levers would move. Disconnect your reverse rod and move the reverse lever to its forward position. With that lever forward and the other two straight up, you should be in neutral and ready to hook things back up. You may have to move the main lever to neutral to get the reverse lever to move or vise versa. I donít think the trans like being in two gears at one.

Gotcha.  Just don't see how it can since I didn't move any levers on the tranny.  I'll do what you suggested.  Hopefully tomorrow will be a better day.  Thanks. Thumbs Up

Sounds good and good luck. Before you hook any of the trans levers to the rods, make sure your shifter is in neutral and you have the proper side to side movement. With the shifter in neutral, now hook up your levers (two main levers straight up). Let me know if your still having problems and Iíll crawl under my car to verify the neutral position on the reverse lever, thatís the only one Iím not sure of itís neutral position.

It's done!!!!  Big smile Holy crap I wish this had happened to me 5 years ago.  This thing shifts like it is brand new (well, almost)!
No telling how long this thing has been loose.  Now it clicks right into gear and all the rattling and vibrating is GONE!
Damn, I love it when I fix something and it comes out better than before.
Thanks Manchester and Vman!  All it was was the tranny was in 2nd gear.  I couldn't sleep last night thinking it was jammed in 2nd and I wouldn't be able to get it in neutral.
Well, I disconnected the shift lever to 3/4 and reverse, and pulled back on the 1/2 rod and it snicked right in to the veritcal position.  Hooked up the 3/4 and reverse and could shift into all gears.  Party

Can you tell I'm on an adrenaline high?!
Thanks guys, I owe y'all a few beers.  BeerBeerBeerBeer

Congrats !! Glad you got it back together and that itís much better than it was !! For the record, the adjustment tool that Shark was referring to was actually designed to be used to keep this scenario from happening. I have one, used it once and as he stated, it is a major PITA. The good news is it keeps the shifter in neutral while you hook up the rods. Itís also used to adjust the length of the rods to get back to that perfect neutral position. The bad news is how to get it in, and much worse how to get it back out once everything is hooked up. Now go out and enjoy your new four speed !!
