Looks like the experts agree on DJ5. I sure as heck don't know. How big an engine would one of those small mailtrucks accommodate? Looks like a pretty healthy exhaust pipe underneath. If it weren't for that, I'd think it was a little kit car.
I used to drive a RHD mail Jeep---the odd van-shaped version, flat front with sloping windshield.....gutless wonder. I lived in a town that had a stop light at a major intersection, at the bottom of what they called "a bench" .....a vertical step up of maybe 100-200' elevation as you moved out of the river plain and progressively more toward the desert.
It was the Christmas rush...and the trucks were all stuffed bulgingly full....floor to top, package tray over the motor clear to the back door....
In those days (about 1968), those mail Jeeps still had, IIRC, the old 60hp CJ2 engine but detuned for some odd reason.
Well....stop, overloaded at the bottom of a notorius yet only moderately challenging climb.....and with the 2 speed slipo- jerkomatics sometimes you would get pretty much stuck in between shift points and have to back down the hill....into the face of oncoming traffic....
You probably can guess where this is headed....
but I ~DID~ make it up the hill....took several minutes, there was a huge billowing cloud of hot fumes from underneath.....and I mentioned to the shift boss a little trouble getting it up the hill when finally returning to base command.
They retired that old dog and gave me a new truck the next time. Yea!!!!
get in--buckle up--hang on

Too bad I just bought a 2012 JKUR or I would've stopped and made an offer. No I'm serious.
When the original CJ's came out like the 2A/3A, there were several Hard tops available on the market. Even Sears made one available via their catalog.
My '46 (pictured below my name) was going to have a hard top exactly like this one ( Recent image by BAD_ROD on Photobucket ) made of solid steel. I had the inside rhino lined to keep out some of the squeak and rattle of the big hung of tin.
Ultimately, I decided to go with a soft-top by Tiger top. Sold the steal hard top for 3 times what I bought it for.
As for deliver jeeps (DJ), I "almost" bought a DJ-3A for cheap as a possible cheap crawler build. Unfortunately, no 4 wheel drive...as in, no t/c. Strictly 2wd. It wouldn't have been that hard, but at the time, I was low on cash with my 2A's build.
