Adam....I got a D44 from a 1979 k10 half ton. But the vin on the truck says 2wd. so someone put the d44 under this truck. the d44 i got was on a half ton 2wd truck, and it had 8 lug hubs which are from a 3/4 chevy. so i went to the junk yard again and found a d44 with 6 lugs from a 1/2 ton. which i was supposed to get the first time. so i solved the problem. i have both front ends now and ones 8 lug and ones 6 lug. and i found brimbo brakes that will fit a 85 chevy pick up, they should fit nicely. Anyways, i have an extra front end if anyone you know has a t100 that they want to do a sas on. anyways thanks for all the info and about the engine questions, is there anyway around the supercharger except for getting a later model t100 lol.
