Mine is the "Drop in" B-Body Tilt for stock power steering that uses the stock column clamp. You have to use their A-body floor plate. Its a drop in except:
1. You need an aftermarket steering wheel. Stock will fit but you need to grind the key out of the stock wheel. Even then there are gaps between the column and wheel. Basically this is a GM column made to fit a Mopar.
2. The D shaft needs cut gown to fit an A-body. It comes out by removing the zerk fitting. Mock, measure and cut.
Being your running a rack I don't know what would work there.
