With the special socket i was finally able to break those knuckles loose, it took some real effort. Full reverse of the ½ drive titanium Ingersoll, WD40 and lightly striking the inner C with a hammer the inner nuts let loose one by one. The left side of Kevin's has a wedge shaped shim under the outer nut, time for some research.
hey toast, Seems like another little Y made of tube would made a nice tandem axle stand judging from that last photo.
on the exhaust thing... Mad hatter does great exhaust work in my opinion, kevin's had work done there and might have an opinion too. If you pay cash and be cool, sometimes they're super cool. Likely super cool anyhow if you say you're from Prescott.
