I recently bought another flatty. A 47 cj2a. Its still sporting the original L-head (which will be staying) a t90 and a d18, for axles its got a 19 spline tapered 2 piece D44 rear and a D27 front from an early 5. It on some 33's which will also be staying.
Here's some pics (also shown is my 51 cj3a resto project)
I am planning on swapping the t90a for the slightly better (lower) geared first of a t90c, which I already have the parts for. For a transfer case I will be using a hybrid d18/d20 set-up for twin sticks that will allow independant use of either axle.
I will be swapping to a later flanged D44 from a cj5 and a disc braked D30 also from a cj5. Both with 5.38 gears and lockers.
I have already completed a saginaw p/s swap. I will also be swapping in Herm the overdrive guy's master cylinder kit to go with my new disc brakes.
Building it for moderate or less trails. Going for reliable, fun little rig!
more pics to come when I get some free time to work on it.
Here is another pic of the 51 with the new panels on the body tub for good measure
I will probably catch alot of flack for my motor choice, but I like the simple little engines, got kind of a soft spot for them. I guess if I was rich, I'd be called eccentric, but I am not rich, so I am just crazy.
