I am new from Missouri, and I am looking at a 1992 K2500, I am curious about what to look for on these rides. It has the 8 lug wheels, a 5.7L with the granny low 5 speed. I have always been a square body man, but am looking to get this truck for pulling stuff and take the older kids fishing and stuff. Was the G80 option common in these rigs? I have not looked at it, what are the probability it has a 14BFF, as opposed to the 14BSF?
