Regarding the brake pedal, I'm sure the hole in the frame is now grossly wallowed-out... even a new pedal would have a sloppy fit. I may just have to drill or ream the hole in the frame, then weld in a sleeve machined to the proper size.
I'll start work on the swingarm bolt when all the crucial stuff is done. I can just lay the bike on its side in the garage and lay the PB Blaster to it, for weeks if need be. I have an air chisel with blunt drift bits... if I can work the thing back and forth in a sea of penetrating oil, maybe something will come of it. I'm not holding out for an easy job of it though. I don't believe the bike spent much time in the desert, but was in the southeastern USA most of its life... humid summers and frequent mud on the trails, not to mention PO's pressure-washing the bike, blasting water into the bearings and bushings.
It may take me a while, but I'll get it. I've been in tighter spots than this.
