    5.3l auto to zf-6 6 speed

    I'm in the process of building a 54 GMC pickup and have a 5.3 from a 02 and am have a zf-6 6 speed from a 92 vette that i want to use. My prob is the flywheel bolts...the bolts from the vette are fine thread but the crank on the 5.3 is course thread!? Will the flywheel bolts for a 5sp truck work? Please help!

    I don't see why it wouldn't work. People use 5 speed truck flywheels with t56s.
