'71 Commando center-stand "lugs"

My bike is missing what I guess to be "pegs" which fit into round holes in the center-stand , which serve to stop the stand from over-rotating. Can anyone describe what they look like and a made of? Looks like the previous owner-restorer removed them

The 1971 parts diagram shows what appears to be a square lug on the side that is seen? Here's the stand area parts diagram from Old Britts: http://www.oldbritts.com/1971_g9.html

I don't know if those lugs were pegged (and welded?) or not? Perhaps some of our other members will know? The later stands were certainly made stronger, and the stops were welded-on plates.
