Once I get the pegs and pins in, I'm taking the frame up to a machine shop so they can refurbish the right side peg mount. I have a NOS left side mount so that side is golden. The shop will weld on a little material onto the existing tabs, plus probably weld a little around the pin hole in both tabs.. then drill it back out and file everything down to fit the new OEM pegs.
Wish I had a shop that could soda blast parts local to me. A powder coating place I use wants to glass bead the cases, but I'm not sure I want that look. I hear soda blasting is the way to go.
