I’ve just bought a vara 125 that arrives today. Left foot peg and swing bolt are broken, I bought some universal ones from eBay. I’ll let you know how it goes putting on if I remember
I never got back online to update, I attempted to do this myself and failed because I did not have a 22mm socket. everything up to 21mm

Anyway, I had a choice, take it to the garage or go buy the bits, I opted for the garage, £15 and all sorted, turns out, had I gone to buy 1 22mm socket I would have failed again, as you need two of them to tighten the bar from the other side.
Problem you will have with yours is that the left side, you need to pull the bar out to remove the holder which means your swing arm will fall off, I read a tip that recommended buying a new bolt and using that to knock the other bolt out and when you are done, knock it back in again.
Good luck with your repairs.
