on a 2000 and up silveradp/sierra will the drive shaft clear the cab with a 3.5 inch bd. i don't have a tranny in the truck or a drive shaft i was just eyeballin it last night and it looked close
did you do a stock floor or traditional? if you did a traditional the floor is in the same place as teh driveshaft is in the same place as well, but if you stockfloored it you may have to notch your tranny tunnel for it.
