I had an "aha" moment last night as I was going to bed and realized I don't need those "wings" on the back of the top deck. Also, the deck is too high in the front for the body to go on the whole way, so I need to rework that as well.
These should also help quite a bit on this project. I'll get the final configuration mocked up today so I know what heights I need to order.
This is really getting fun
