Same here, if i could have bought one i would have as well. Mine started out as just replacing the floor. door posts also shot. door posts connected to the inner rockers, inner rockers connected to the kick panels, kick panels connected to the inner fenders..............Im afraid to say how much $ i have into this thing and it is not even painted yet!!!
I'm in MI too let me know if i can help with questions (i've learned a lot... some the hard way)
This is a good site and the people here are top notch. They know what they are doing.
