new GM steering box

Anybody every use, or know somebody who has, the Lares 974 Rockauto box? 

The Rockauto 974 box is for a rebuild of your existing box. I ordered it will sending my marked box in to see if I get the same  one back with a quick ratio. I'll post my results.

I have not. I installed a power steering pressure reducing valve but have only driven the car around my neighborhood to try it out. I think I'll keep it. I also will play around with adjusting the lash on the original steering box to try to take some of the play out of it. If I still am not satisfied with the way the car drives I'll probably have the box rebuilt to the newer specs sometime next year.

I'm a proponent of using the Saginaw box from mid-90s Jeep Cherokees. Two of the three bolts fit directly and it's no big deal to make an adapter for the third out of plate steel as the mounting hole is only an inch or two away from where it needs to be.  Rag joint and hose fittings went to metric after 1979 or so, but you can either buy adapters or have new ends put on your hoses, and it's not a bad idea to replace the rag joint anyway.  If I can do it, anyone can.  The steering ratio and effort are just about perfect for my '72 Javelin and the internal stops are just right.  I think I paid $60 for mine at the local Pick n' Pull and another $40 or so for the rag joint. The local Napa store put new fittings on my old hoses for me.

Mine was from a 94 Cherokee. 92-96 Cherokee is what I heard will work. Not sure about differences between Cherokee and Grand Cherokee boxes, but would be worth checking into to see if the 3rd bolt of GC box lines up better than the Cherokee box. I've bought the material but haven't actually finished the spacer plate yet (been driving it that way for a year & need to get back to it!) It really just needs to be a small steel spacer with two holes in it, one that bolts to steering box and the other that bolts to the original AMC mounting bracket. In the Cherokee the box bolts directly to the frame rail, but you'll need to use the Javelin's original mounting bracket.

Follow the link below to my project thread and you'll see what I did. Scroll down that page and you'll find part numbers there too.
