i was wondering if anyone knows if there is a difference between the cab on an 1986 d250 and the cabs on 1990-1993 150 and 100, the entire bottom of mine is rusted out and i decided i would be better off replacing it. found 2 trucks at the junk yards with cabs that have little to no rust, they appear to be the same as mine but i wanted to know if my dash will fit and they will bolt up the same as my 86 before i go get one
