Why and why not? I am running a 1952 Desoto Hemi with a 1957 Imperial generator with the power steering pump on the back so I was looking for a gear box that would fit to utilize the pump. Looking at all the pictures on EBay, it looked like the only option was a Mercedes gear box because of size. So I looked on Craigs list and found one that is small and may work with my 1940 Ford cross steer set up. I went and got the whole set up from the power steering pump, gear box and all the rods to the spindles for $60.00 it even has a dampener. I think with the weight of the hemi and getting a bit lazy, it would be nice to steer into tight spots with little effort and to use the old pump would be cool.
