Heh I've done a few tubbed cars myself - it's well more than a few hundred.
Personally, I would want to un-hack the car - I don't consider it usable for racing as-is. Especially since it's a 340 car? And was it a Swinger or a GTS?
I'm considering the car, but the price would have to come down...that rear frame/suspension isn't an asset to me, more of a headache that needs redone before the car can be finished.
