77 sb with DM/LS swap... tunnel cab??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Anyone out there running an LS/700r4 with PB's Dropmember, and had to tunnel the cab? Nate said the trans angle should be around -5 degrees. Well I can get it to about -7*/-8* before it hits the cab floor.

My truck was originally set up with a 2-piece drive shaft, but I'm switching to a one piece. Looks like I will definitely need to cut the carrier bearing crossmember to clear, but also looks like the drive shaft will hit the cab floor. Is this something anyone else has ran into???

Thanks,
Justin
