Finally got the time to take out the bench seat and tear out the carpet, and much to no one's surprise the floors are rotted:
driver side (it's like paper)
the passenger side is a bit better
good thing I have some new floorpans coming on Friday
However, its not all bad news, look what I got for free:
89 eliminator, 2wd
the engine doesn't leak at all, but there is no interior, and the floors are about as bad as what I already have, but the "frame" is still solid
the bed is in better shape than the black one so I am going to swap it over, yank the engine and tranny (its a pukeguts but it still shifts smooth), take everything else I need out of it to put on the black one and give the left overs away, all I hope to be left with is the cab and "frame"
