Driveshaft shortening...help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm in the midst of swapping a 700r4 into my '72, but after removing the TH350 (short tailshaft) I have found the driveshaft will have to be shortened. My question is how much will it have to be shortened?
From what I can tell it will need to be shortened 2-2.5 inches, but I was hoping someone here has done this and can enlighten me.

The PO

said he had a 700 in the 'burb for a short time without shortening the shaft (probably the reason for it being in a short time,LOL), but after seeing the difference in the length of the trannies I have a hard time believing it.
