Whats the difference

I remember warning panels on the dash restricting speed around corners to under 20 MPH. nobody paid a lick of attention to them

ROPS: Roll Over Protection System. A friend of mine that was in Panama said that the vehicles spent more time using the ROPS than the tires.

The main external differences are in the front fenders and the turn signal / tail light set-up. M151A1 had flat ront fenders with turn signals mounted in top in bullet shaped housings, blackout marker lights in the front grill and WWII style split tail lights. Also, the rear tire opening makes a straight line from the upper level to the rear plate. The front windshield was also split vertically down the middle by a metal brace. The suspension made the vehicle very succeptibe to rollovers. This is the main reason why the A2 version was developed.
M151A1:



The A2 incorporated the new, safer rear suspension and the following external differences:
New NATO turn signals and tail lights, resulting in a new front fender with a noticable bulge at the bottom and blackout marker lights being incorporated into turn signals / tail lights.
One piece front windshield.
A step in the rear wheel well profile for added strength and to attach a tie down shackle.

M151A2:



Hope that clears it up.
