Got the motor mounts done. I used a couple billet light mount brackets I got from a dune buggy place and some 3/16" plate. 1/8" seemed too flimsy to me. Had to get out the round file and change the angle of dangle of the mounts to give the motor the right slant to fit under the tank. I will probably turn the front mount around so the clamp is above the motor mounting boss, but this gets things close enough so I can now lay out and fab the jackshaft.
