There's a number of nice detail pictures that show some nice work. Note the modern running gear (likely mid 70s CJ-5 running gear). I can't say I'm a fan of the tranny/tc mount — it's a single bar that just waiting to be hit by a rock. It most definitely needs a skid plate of some kind. I think the body is fiberglass, but I"m not entirely sure.
"Motoexotica is proud to offer this 1947 Willy's CJ-A2 Jeep 4×4. This Jeep has a 3 speed automatic transmission with newer big 33 inch mud tires. This tough Jeep is ready to play in the mud or just go for a drive. It has power steering, power brakes and a working heater!
The motor is Buick 231 Cu In 3.8 liter V6. It is fun to drive with the GM 3 speed Turbo Automatic Transmission. The motor runs strong. It has a quadrajet 4-barrel carb with an aluminum Edelbrock air intake and a Jeep transfer case with a Dana 44 rear-end."
