Parting it out, you could get some for the motor and the front clip, and really the rest is only usable for another '60 M-M ambulance, of which there aren't many - so most of it would be scrapped.
as stated most of the parts will only fit a 60 MM and you'll still have some when your old and gray.
Clearing inaccuracies up so others don't view these statements in the future and hold them as true, nothing more.
From personal hands-on experience and other than obvious external '60 components:
-Fenders & hood sheetmetal interchange with '59. Trim holes change between years and models. Not commercial chassis specific. Headlights & bezels are '59-'60 Cadillac (all).
-All '59-'62 MM glass is interchangeable (windshield through '64, ambulance etchings changed for '61-'62).
-All five '59-'62 MM doors are interchangeable ('61-'62 skeg moldings are bolt on.)
-Side upper door frames interchange between like MM models from '59-'62.
-Medium height roof stamping used from '59-'62 (at least).
-Rear compartment remained an unchanged MM ambulance option in designs from '59-'62. Interior hardware used throughout carried on longer.
-'59-'62 MM partition glass and molding are interchangeable.
-Firewall is '59-'64.
-Dash is '60 only and commercial chassis specific. Commercial chassis dashes have different grain, although a passenger car dash is same size/shape.
-Skirts are '60 CDV. Coach builders sometimes modified mounts slightly from OEM.
In short, a large percentage will work for '59-'62 MM. ('63 brought new redesign.) Yes, you'd probably still have some parts when you're old and gray. But this still isn't a parts car. Anyone thinking as such gets lumped with Ecto clone mentality on principle.
