my uncle has a 77 ambulance that he used to plow snow with until the tranny went out. it only has 32000 miles on it. i am thinking of buying it off of him but i have some questions and i hope somebody here can answer them. first how rare are these? i plan on a little lift and cut to fit 35s and dont want to hack something that is valuable. what axles are in these and what are the gear ratios? is the suspension the same as the powerwagons of that time? i think it would look great lifted and plan on using as a dirtbike hauler/offroader. the box on the back is huge.
