I have 1967 GMC short bed on a 1972 C10 leaf spring frame and a 2003 Vortec 4.8L and a 4L60e Tran.. I did not get the pedal and TAC module with the motor. I have a junkyard close but I'm not sure which one to get. My motor has green/blue connectors on the ECU so I know it's 2003. If I can get a Tac module # it would be very helpful.
Did see on ltlswap.com that Tac# 12573058 or #12588923 would work but all I see at the junkyard are #12573059.
Somebody help I'm ready to drive this thing.
