Transfer look right, but the front axle should have NAPCO cast into the tube next to the differential housing.

Thanks for the link, I'll check it out.
The front axle has Napco has onto it, on the drivers side.

I don't have the truck here, and the pic I have of the lift block isn't very close up. The blocks do have bump stop pads cast into them.

This is the direction I'm leaning. Luckily this won't be a full resto truck, so if it's not a true Napco, that's ok.
