I just finally got my mkIII on the streets yesterday when as soon as i took off i heard a loud pop from the back end and alot of moving. I immediately came home and jacked it up and saw that the rear differential support was broken and everything was moving around. I take this is a common problem with these older supras? There is an N/A in my local junk yard but i wanted to know if these would be interchangeable between the N/A and the Turbo.
