I just found a guy that is looking to get rid of a 1980 1ton daully 4x4 with plow. The truck is free . What might this truck likely have on it for engine/tranny/tc/axles. also will I beable to use the plow, will it bolt up to a blazer frame or are the hook ups different. Last question how hard is it to change from a drw to a srw. Thanks for the help.
