I will not be lengthening the drive shaft. The engine will be shifted toward the tail the same distance the chassis is stretched. The body does not include mounting points or anything like that. I will have to put those in myself. Each builder tends to do things differently, and there is no right or wrong way. Wait, there is a wrong way. lol. The way that doesn't work is the wrong way. But you know what I mean. Many builders have come before me, and I will be following their lead, taking the good and ignoring the bad. I'm going to be doing almost all of the metalwork myself. The initial stretch will be done by a pro, as that is ONE set of welds I cannot afford to get wrong.
