I found a set of motor mount adapters at TPI parts, that are 3 position, 1 in. forward, standard, or 1 in. back position. I purchased them, and they are very well made, came with all grade 8 hardware. I installed the engine in the 1in. back position, and it lined up perfect, it put the trans exactly in the original position, no elongating holes or anything. The driveshaft fits perfect.
