I have an 84 GMC Jimmy. I've only had it about a month and a half. The rear right between the gas filler and the talgate(that corner) is rusted out on the inside(the bed). Pretty much shot to hell. The drivers side in the same area seems ok. How much hell am I in? How much work is involved in fixing this? And with that, how much do you think a body shop would cost(hi-lo)? The other vehicle is minor and I can live with it till I can get it fixed, but I'd really like to get this rear hole fixed so the rain will stay on the outside where it belongs.
