Just got my tail light gaskets, that was definitely the cause of the leaking trunk and rust. Pretty amazing the difference between the new ones and the 22 year old shrunken, dry rotted, and cracked originals.
Now onto the body work, I might just end up painting the rear panel black for now.
I might just get a sound clip the next time I turn it on, for as old as it is, it's fired up on the first crank every time.
