Are you swapping in the trackick engine AND tranny, or just the engine?
If it is just the engine, then you should be using an adapter plate between the engine and tranny, and you don't reuse the metal spacer.
If you are swapping in the engine and tranny, then make sure you have the circular dowels that fit around the engine to tranny bolts.....they make sure the spacer plate is in the correct place, for everything to line up correctly.
