Since I raised the Motor/Transmission combo..I needed to give enough room for driveshaft clearance, especially at the rear of the Transmission.
Since the Combo was raised about 3/4" I decided to stick with my 1.5" precut strips I used in the engine bay and keep everything the same number instead of 1 1/2" here and 2" there and then 3/4" over here (you get the idea)....nice and uniformed.
