All the early CJ5 tops were this way with the doors. Of course, none of them were long like these. They all looked super squished as the early short fender 5s were so short all around. They only had an 81 inch wheelbase from the factory.
You just generally don't see a hard top on many of the Early models. So it really makes them look different compared to the soft top most people run.
technically its ***led as an m38a1 but the m38s have a lot of small differences. Battery box on the cowl (I did make the plate to bring it back, but it wasn't going to work with the AC system so I left it off) no JEEP stampings, the round indentation for mounting the military anti aircraft spot light on the passenger side cowl, insert headlights and blinkers (I didn't want to cut up an m38 grille) cut outs for a snorkel on the hood(only came on short hoods, and very rare). They also got a large gas filler cutout and cap on the drivers side for filling with Jerry cans. Which is why my filler looks different. And a split windshield that pops out at the bottom for ventilation (jeep shown doesn't have the correct safari windshield).
the military CJ ambulance is even weirder. A huge cutout on the passenger side for stretchers, but a regular CJ5 door on the drivers side. Round spotlight mount is there, but no provisions to actually mount the light.
of course at this point, the jeep is just a mutt. Some old features, some new, some military, some not. But a whole lot of stuff to make you wonder which model it is. Long dissertation for your question, but I really enjoy the unique-ness of the Early cj's.
