I need one too. I have been looking into it and they can be used they (The later ones) are much better because they have a bearing instead of a peg! I think the mount must be modified.

Actually both styles are interchangeable but the 73-79 has a larger pitman arm spline. I know because I pulled my steering box and the pitman arms were different. I replaced my box with a TRW box and boy does it ever make a difference in turning. I used a synthetic gear box oil and it works like a Swiss Watch.

Don't count on any of the rebuilt units lasting very long either. Some go as far as just cleaning them and painting them only.

the early box is rebuildable with replacement parts if you can find them. Right now the peg is what is needed most often. When it stops turning it flat spots. A good machinist could make them and test an old one for Rockwell then duplicate.

The late boxes were not designed to be rebuildable but they are. They are however either good or worn out when you inspect them. Seals and bearings are available. As long as they are a little tighter in center than outlying they will work 90% as well as when new. They were made by Gemmer then the design licensed to ZF. Gemmer built steering boxes for everything from trucks to Ferrari's from the 1930's on so they are well designed.

To my knowledge from what I have read there is no one who remanufactures them at a level I would be content with. My opinion of the definition of "rebuilt" may be different than yours. Too many horror stories here of rebuilt boxes that were new paint on the outside and old grease on the inside. I've rebuilt a few and they can be rebuilt if one takes the time to get new high quality bearings and seals.

well i did it . no big deal at all and it works awesome. no crappy "rebuilt" box here! i took some pics of how i did it if anybodys interested.
the box is a trw new box . trw is casted in it

first i made a cardboard template of the box and all the holes . i use poster board. i put it up on the frame and slide 2 bolts that lined up and marked the center hole so i could open it up

i used my die grinder to open the hole . its not a whole lot bigger than what is already there. did not take long at all. then i drilled out the spot welds that held in the tube inside the frame for the hole furthest toward the rear

then i pried the tube out.

next i took the template i made and marked where the rear hole needs to be and used my die grinder to slot out the og hole to the new one

both sides

i put the box up in there but the top rear hole was off just a tiny bit so i used my angle drill to clean the hole out

i put the tube back inside the frame after i sanded off the spotwelds on it and slid all th bolts in the box to line the tube up

pulled the rear bolt out so i could tack the tube in

welded up!

painted the frame up and bolted the box in. i replaced the rag joint as well. the pitman arm for this box has a bigger splined hole as well the nut is larger . i bought a used pitman arm from a 74-later bus . he gave me the nut and a thin flat washer that you bend around the pitman arm and the nut to keep it from backing off. both the rag joint and the drag link bolted right up. works great . not as good as the cavalier rack i put in my split bus but this was vary easy and youll have a new box you can count on
