On of my first jeeps was a 1942 CJ2A, and yours looks pretty darn complete. I swapped the windshield for a 3A, as the soft top seals better. The old wishbone steering is flat out scary as your speed increases, so I swapped the box to a Saginaw power steering unit and dumped the wishbone for a normal tie rod/drag link system and just built power steering pump brackets.
I had three transmissions, as that was the weak link, so constantly lost the input shaft needle bearings. I finally figured out that if I shimmed the main shaft at the rear right before the bearing to eliminate excess play between the main shaft and input shaft, the transmissions would last behind the small block chevy I had swapped into the jeep. The Dana 18 transfer case is solid, but it's weird having the drive lines both offset to the passenger side.
Enjoy the project. I had a ton of fun in my 2A jeep, but had to sell it after everything was fixed as I needed to start college...
