I'm using a manual box from a Camaro in my Gremlin, just need the AMC manual pitman arm. The input shaft sticks out a long way from the manual box so that they are dimensionally the same when it comes to steering columns:

Not sure exactly, but 401MatadorCoupe stated that power steering rag joint coupler is different? Something to do about clocking the steering shaft.

Somebody had a problem clocking their steering wheel with a power steering box.

The rag joint may need to be exchanged out depending on fitment and possibly model year with the AMC car.

When putting P.S. in a truck I remember something about using half of the rag joint from the box and the other half from the shaft end so that kind of stuff is possible.

I think the ragjoint is different, and the Pittman arm is different. You need the aluminium spacer and the correct bolts as well... I did this swap..but in my case it was a 1972 Gremlin box into a 80 AMX.. It bolted right in.

Steering wheels go on in any position, do they not? That should take care of any 'clocking' problems.

20 years ago my little gremlin had power steering. Then I read an article about loosing horsepower to extra pulleys, a.c. too. So I removed that junk.

My steering box I looped a piece of the hose I cut from the pump into the other fitting on the box. And wah la.. manual steering.
Do what you want, but for zero dollars ^ that's what I did

The steering wheel will go on any position, very true.  HOWEVER, on manual steering box the shaft is rag joint shaft is smaller, so you need a different rag joint (smaller diameter on Manual steering).

Secondly, on a 70 up Saginaw Steering Column there is a lock plate under the steering wheel, the lock plate has a master spline, which then "clocks" the Horn slip ring and contact pin to the steering wheel, which has a hole in about 10 o'clock position.  The main steering shaft at the steering wheel side has a strike mark in it, that is supposed to be at 12 o'clock, when wheel is installed.  Once it is centered up top, turn the key to the off position and the column is now locked centered.

Next the steering box must be Centered in its movement from full left to full right.......put it in the center and the rag joint which on Manual Steering cars has no master spline, should be installed at that locked column location, with box centered.  If this is not followed you can end up with a "uncenterable" steering wheel, with car in correct alignment (toe) and can not be corrected by the tie rod end adjustment sleeves.

I hope this makes sense.

On Power Steering cars, it has a master spline, dictated by the rag joint spline squeeze bolt, that keeps the box in relative close alignment.  

One extra note, none of this pertains to a 69 and prior car, since they do not have the steering column locking plate to cause alignment issues.

Thanks for the clarification. It matters to others but I didn't know because my collector vehicles will more than likely always be older than 1970. I guess it is what one grows up with as a kid.
