Boxster50 - well, you're gonna love this... actually neither the kit nor the motor came with actual mounts :/ Just pieces the mounts bolt to so that is another piece of the puzzle to figure out! In the pictures they sent me the motor itself has aluminum supports from the motor down to what appear to be large rubber mounts, not sure if they are the Chevy mounts or aftermarket. The rear mounts for the transmission appear to be some sort of solid mount from what I can see. Not sure if the factory mounts would work back there or not... here are a few of their pics...
