tranny swap question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 350/350 combo in my 66 SWB. Want to put in a 700r4 but use my existing driveshaft. Is it possible to move the motor mounts forward on the frame to compensate for the extra length of the 700r4 and still be able to use my old driveshaft? Is this more trouble/money than just having a custom driveshaft made. Don't really want to cut my original down, no one around here that actually balances it. They just cut it on a lathe and weld it back together. Others have told me the results are not always that good.
