[QUOTE=frstvette]say larry to get the gearbox out do you have to drop the steering wheel? I know it has two bolts on the side and then at the control valve[/QUOTE]  

Frank, you didn't say if you have an auto trans or manual. On my '81 w/ 4 spd. I had to lift the steering box out by the alternator, otherwise you'd have to remove the clutch linkage to drop it out the bottom. May not be an issue with an auto trans.

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

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 was talking about power steering and non power steering. dont they make non power steering gear boxes?

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
