I have manual trans so do I slide the steering wheel back then pull it out?

There's a bolt going sideways through the upper rag joint collar, once that's loose, if you spray some penetrating oil on the shaft right there and help spread the collar open a little, the steering box should pull off the steering column without pulling the column back up inside the dash. The rag joint will stay with the steering box.

That works.  I leave the rag joint on the column, and, once the box is unbolted from the frame, slide it down and off.  If you buy a rebuilt or have yours rebuilt, you need to take the rag joint off the box anyway.  And it is pretty easy to take apart the little bit of clutch linkage in the way if that seems easier than getting it out the top.

is the gear box the same for  power steering and non power steering? Seems like the gear ratio should be different.

I'm with you Frank. Mine felt like close ratio compared to my wifes w/ auto tranny. But I'm sorry I don't know for certain.

I don't know that for sure, but it would make sense to me that it would be an option. Sorry.

All steering gear boxes from '63 to '82 had the same ratio, power or non.  There was one change in 1968 (?), in the input spline, but otherwise it is the exact same part, power or manual.

should not take long to wear out a gearbox because I could barely turn the steering wheel to get in the drive way or going slow around sharp turns

ok I have every thing loose. Ran into one problem. I have headers and gear box will not come out. How hard is it to talke that lever on the bottom of the gear box off? What size bolt is that? My only choice is to take off lever or headers. lol I sure hope I can put all this stuff back together. I know one thing if not for you all guys here I would have been stuck long time a go. I sure thank all of you on this forum

dohWits End
The pitman arm takes a stout puller to get it off, You can usually rent/borrow one from your local auto parts place.
The nut is 1 5/16", I think...it's been a while since I've pulled one off.
Good Luck with it, and be careful...that thing is fairly heavy!
