I have a question for all the guys with 77-79 mark Vs who redid their suspension: where in the world can you find polyurethane bushings for the rear suspension? Trailing arms, sway bar bushings, etc. when I had my 79 I ran into this problem. I want to buy another one but want to avoid this problem since hydraulics can eat up bushings. You can get regular rear bushings for these cars at rareparts.com. Polyurethane bushings for the front suspension are easy to find but where are the polyurethane bushings for the rear suspension???
