Iknowright. The least they coulda done is put a bearing assembly on the main rotator! Before I repurposed mine, that was my complaint too. That 6 cyl sticks out so far there is no help from the engine in rotating it for sure. The other as Tim said, you have to be a rocket scientist to figure out how those goofy mounts work. I might stop and take the time to address that before using it. Make an adapter that just works for the GM 6.
