I put in a Hotchkis setup in the rear of my 81. Now Im thinking about doing the front end over before I put the motor back in. My question is should I bother putting in poly bushings when I do the front or just replace them with OEM rubber ? When I did the subframe over in my 72 Nova the guys at PST told me the OEM bushings would give the car a smoother ride. Will it cause any problems mixing front and rear ? Also I put in poly motor mounts. Do I use a matching transmission mount ??
