You're correct, it's very close. I actually did grind a little off yesterday, and they got really close. I was just afraid to go too far with the grinder. I almost think l could try installing them on the bushings with the long bolt first, and then install the mounts on the motor. I dunno. What do you think ? Also, are the clamshell mounts with the bushings left and right specific ? Im almost positive l installed them exactly like I took them off, but lve done so much in the past few days I'm even sure now. With it being so close, l feel like your idea is very good.
