Crown vic setup will be done on another chassis under my 83.
My thinking is, without any doubt in my mind, I can make this work, and offer modded exchange basis control arms, and the rest of the parts together to do a up to 6 inch adjustable front drop without using dropped spindles, anybody with reasonable fabrication skills could do this mod. You would get proper suspension geometry, rack and pinion steering with minimal to no bump steer, and stock quality ride, along with better handling.
I may even go so far as to offer a 8 inch drop rear kit complete with sway bars.
I am sure these trucks can be made to handle very well. It just takes a well thought out system to all work together, and not ride like a farm wagon.
