The one i built is pretty much all prewar except the exhaust headers. The flatly fits nice and i am also using the model a rearend. The flatly doesn’t have enough power to destroy the rear unless your beating the snot out of it or dumping the clutch. I had planned on driving it to the swap this weekend but life got in the way lol. This can be yours for 12. and no need to screw up another Model A
The HAMB would be a better place for hotrod questions
