This M170 ambulance looks in great condition for restoration with only 16,000+ miles.  Plenty of good pictures of it on eBay.

I’ve never heard of this type of jeep (this is becoming an all to familiar statement!). Here’s some more info on this jeep from the Olive-drab.com website

“I am moving and need to get rid on this project, its a military ambulance. It comes with a fuel injected 4.3 with NV 3500 and NV 231 case, Wiring harness and computer, steering column, peddle assembly, Ford 9″ with Strange 31 spline shafts, HP Dana 30, the original top and doors (brand new), tailgate, windshield frame, hood, grill, gas tank, fenders.

Here is a pic of the M-170.  Note the extra wide entrance on the passenger side vs.  the normal looking CJ-5 looking entrance on driver’s side.
