I have an 8ba in my '39 p/u. You need a truck (or rear sump Merc) pan. Assuming the motor in the Shoe Box was narrow belt. Truck pumps are wide belt. Are you changing the crank and generator pulleys to wide belt? My 8ba had narrow belts so I used the hard to find narrow belt Merc Pumps. They appear similar to a truck pump but the mounting pads are a different height. The Merc pumps require a U shaped spacer between the pump mounting tab and the rubber biscuit mount. Doubt the Shoe Box radiator would work.
