I'll have to look into the aluminum.
Oh Joebaby, almost forgot to tell you. I did have to move my brake from the rear of the tranny to the front of the tranny because it was hitting the flywheel. I had to make a new brake linkage since it was longer.
Do you get full gear contant with your two speed and clutch bell? It looks like my motor should be about 1/16" forward to get %100 contact. (or my spurs about 1/16" back)
