Backhalving?
I didn't back half my Duster because I didn't want to cut up an original 340 4 speed car. So I took the engine, trans and third member and traded it to my son for his Scamp. I never would have done this to the Duster, but the Scamp isn't worth what the Duster is.
There is a thread in the members restoration area (I know, it's not a restoration) with practically the entire build of this car.
