sharp eyed readers will note that the suburban had 8 lug wheels .
1500 suburbans only came with 6 lug wheels .
so this conversion probably had a conversion to the 2500 front and rear axles .
the 2500 also had a considerably larger rear differential , very large rear Drum brakes in that year . I'm guessing that is about a 1995 to 1996 model .
in any event , nice conversion .
