Yep! That's the way to do it with the 70s and 80s cabs in an 8ft bed! Running two pallets end to end, screwed together the cab will fit inbetween the wheel wells, and the tran tunnel hump goes rite over the wheelwell, so don't really need any dunnage underneath. Using 8ft fork extensions to run through the pallets works great. 6ft bed hauling, you have to raise it up just a bit..and tailgate down.

I bet the 94 cabs would be pretty similar, if not, raise it will some 4x4 or 6x6s or whatever.
