Early A front suspension with rack & pinion steering
You can build one by yourself much cheaper than RMS :)
I use Viper front shocks, A-body 1975 spindle with disk brakes, I wide the frame so it is the same wide as 1975 A-body. A lot of welding and some head ache :) but I think it will be great :)
steering rack is BMW E46 2002.
Ackermann and Bompsteering check :)
