OK, the parts came in. Easy fix, remove c-clip, remove smooth bolt, clean and apply lithium around, then put it back. Although getting the peg through the spring while also trying to get it up to the spring arm hole was a pain. The left peg vs. right peg are different part numbers.
Since if I bought more I would get free shipping, I decided to throw in a new rubber peg cover and installed that also, since my left one was significantly worn. It works on either side, is held by two Philips screws. Way too expensive.
