700R4 Swap, Front driveshaft, K20 pickup

[Jack15T]

Hi Folks, I have a 71Chevy K20 with a 700R4 mated to a NP205. It looks like I am going to have interference problems with the front driveshaft hitting the 700R4 Oil Pan. Has anybody else had this issue and if so a fix for the problem? The transmission and transfer case are in their stock mounting positions. I slid the 454 forward two inches to clear the firewall. The 454 was mated to the TH350 when I bought the truck and the engine was hitting the firewall. I thought problem solved with the longer 700R4. Not so fast.
