Chief,
That is indeed a tragic tale. I am so sorry and I do feel your pain. Last night I was fitting my block under the Shelby and test fit it backwards. I made my cuts to later realize I had reversed the front and the rears. I guess I could run it backwards, but our friends the Mythbusters busted that one for aerodynamics. I ordered another block and hope to be ready still for the upcoming race. These are a lot more difficult than I had realized.
On the other models do y'all have to thin the block to have the wheels fit?
