I purchased this 86 SS from a member on here, but have no clue what to do with it. Its has the original engine (305)/transmission (2004r), but not the original paint (use to be white). All the seats needs to be recovered (faded) and I have to clean underneath the car a little. Should I paint it back to the original color, keep the original engine/transmission, upgrade the rear to posi or upgrade the suspension? What would you do?
