Nice truck. The vacuum hookup is pretty simple, look in the book or dealer for similar truck. The 2 speed you got looks good, however, the truck probably will not go any faster, ratios are slow and slower. Looks like not much room for a brownie, don't know what trans. you have now, however, NV-4500 would help top speed or an OD auto.
