Hi, I have this 52 chevy (over 30 years) it has a completely rebuilt and powder coated stock front suspension with disk brakes, a small chevy with TPI, 700R4. Right now it has a power steering box from a cutlass which works and handles fine but I don`t like the way it looks mounted up so high and it is ugly. Does anyone know how and what to use to convert to a power rack (GM) assembly. I don`t want to just go off on my own and end up with another ugly conversion and have somebody say, "why didn`t you do it this way!" after I get it all done. Butch`s rod shop had a lock on these but they are out of business now. Thanks for bearing with me. Harry

I do not know of a rack conversion for your 52. As you well know, a lot of factors play into a SAFE conversion.

1) strength........is the donor vehicle the same weight or heavier ?
2) The length of the rack arm HAS TO BE the same as the A Arm...



Or Bump steer will happen.....

And of course, the overall width of the rack ......must be close to the correct width.....

Is that the lower A-arm you've outlined in the picture to compare to the rack arm? I've been scratching my head trying to figure out how bump steer *doesn't* happen. The upper and lower A-arms are (always? almost always?) unequal length and it looks like the rack has to travel out or in to keep up as the suspension moves up and down. How in the world is bump steer avoided in even unmodified setups?
