Shane,marginal cause the truck is relatively heavy as compared to PU's. But you might be the first one to do the swap in a large truck,so go for it and see what happens.
Rusty, I can't find the photos, it was about 7 years ago.I took a few measurements from the original type clutch housing.Had to grind the cast iron some, then made a bracket from 1/8 inch thick steel,bent it to fit properly.Then bolted the bracket to the 48-53 truck bellhousing.
