After putting about 1.6 million miles in roadtrips on the car this summer(slight exaggeration) I noticed a couple of drips on the driveway. I tagged something pretty good in the Blue Ridge Mountains but didn't notice anything until just now.

The good news is that all the newer stuff that I have upgraded is just fine, bad news is that the rear differential, power steering slave cylinder and transmission pan(again) are leaking. I do need to replace the rear passenger hub assembly too, as the bearings are bad.

Time for a Borgeson. I was going to change the tranny and up the rear end eventually.  Probably go with a 700r4 and 3:70's or Dana's(hello Sarge?).

The need to do is the wheel hub. Everything else can wait until the house is up.

Can't go wrong with a Borgeson box. 
700R4 would be a good choice to replace that 350C.
Our '80-'82 differentials are the aluminum Dana 44 IRS. I had a guy in Texas rebuild mine with genuine Dana 3.54 gears and used a C4 posi unit/carrier. 3.73 would be quite a considerable jump from the stock 2.72's  Be very careful who you have redo your diff. Stay away from Duntov Motors. They build grenades.
As for you rear wheel bearing. I would either get rebuilt wheel bearing assemblies or complete t-arm's. We did complete t-arms on Barb's '78 SA at Ebo's place because they were original and we all felt it was best for her car since she drives it a lot like you do yours.

Keep in mind Bair's offers good quality rebuilding services for both diffs, wheel bearing assemblies and t-arms.

Yeah, Sarge. I'd go with Bair's. I was very impressed with their setup. Do you still have contact info on the guy that did your rear, cars rear?  We had a rear end rebuilt in the '67 Camaro and it blew up after 50 miles.

Dave,
You might look into an air-ride system.  Being 10 miles off the grid in AZ you may need more clearance and a winch on the front bumper!   Wink

Great Idea John. Maybe a 12" lift kit as well!

I'll do some searching this weekend. For some reason the website doesn't come up. He's a member on Digital Corvette. "tracdogg2" Mike is his name.

I like John's suggestion. Take it over to Gas Monkey Garage and have 'em put a lift, air ride and 33's on the vette. LOL

Hey Dave, I would not recommend anything over 3.55:1 gears with the 700r4 trans. The first gear ratio in the trans is 3.08:1. I have 3.55 gears in mine and first is so quick it's crazy. Trust me you will be happy with 3.55's.
Dave

Dave - aside from the leak you have at the diff., have you changed the fluid lately and put in some new posi additive ??

Earlier this year I had so many noises in my '73, I thought I had to change out everything from the door handles back. Bearings, clutches, gears, bushings, you name it. The car not only had the tight turn crunchies, it squeaked and had some funny noises going in a straight line and even over bumps.

Before opening that expensive can of worms, I ran the car up to temp and sucked out as much fluid as I could, then replaced it with two bottles of GM posi additive and topped it off with new 90w. That was followed up by a dozen figure eights in a nearby parking lot, a 10 mile drive on the highway and another dozen figure eights and it has been quiet as a mouse ever since. I was amazed and I can't believe I'm even tempting fate by typing this.

Might be worth a try.

And +1 on not going over the 3:55's. That's what I have with a close ratio 4 speed. Lots of RPM's going down the highway @ 65 MPH. Maintaining 70 for any length of time pushes my comfort level a bit with a 43 year old SB.

Sorry, been away from PC. No problems with systems other than leaking that's why I'll hold off. I am throwing cash into the "ranch" right now, vette is on the back burner.

I will take that advice about the gears and forget about the 3.73's.  Thanks all.

That 4 x 4 vette would be the ticket for easily getting in and out of the ranch in style!!

How come your not considering a Richmond 6 speed for great economy and strength ?

Back and leg problems cause me to look into an auto transmission. I just can't depend on my left leg to bend when it should.

Hey Dave, I hear you on the clutch pedal factor. I can't believe my first C3 was an automatic. 1. Because I liked the red one over the blue 4speed and 2. My size 13's didn't fit down there too well with three pedals. Happy to say my current C3 is a 4 speed, same old size 13's, but I don't drive it every day. I do go from low beams to high beams every time I clutch, back to low beams on the next shift !!
