i got my engine on a stand and no tc for trans yet and i need to send off my stock d shaft from the th350 to get shortened up for use on this 700. i know the 700 is 3 inches longer but since i'm in a time pinch, can i just send out my d shaft to get shortened by 3'' and balanced? who here has done it? also, where can i buy the cheapest 700 crossmember to use so i dont have to chop my old one?
