That tool is a lot thinner at the 12 point part than the Snap-On tool that I have, I don't think you'll have any problems with it, but if you do, a bit of work on a grinding wheel or hand file will solve the problem .
Do you have a 27 mm socket for the swing arm pivot pin jam nuts ?
I tried something that I don't know if I would recommend or not on loosening and tightening the drive shaft bolts .
I forgot to loosen the bolts prior to removing the rear wheel, the usual method is to tighten the adjuster nut on the rear brake until it stops, then push down hard on the rear brake pedal while loosening or tightening the bolts ,
I already had the swing arm ready to come off of the bike, only thing holding it on was the driveshaft bolts .
So I got a long brass drift and placed it into the yoke of the universal joint so I could get the bolts loose, worked great .
I don't know if it cause any harm to the universal joint or not, but if you forget to loosen the bolts up early on in the process, or if the rear brake won't hold, it's an alternative method .
I definitely wouldn't post this on Boxerworks, as it's finally cooled down here in Phoenix, and I don't want to be on the receiving end of the 'flaming' comments that it surely would generate .
