1971 Demon fiberglass fender extensions

cdwmotorsports said
The fender extensions on my 1972 Demon are fiberglass, I believe they're from a set of 1971 Demon fenders. I need to know if anyone knows if either of these studs listed on year one will fit them to bolt them to the fenders I'd appreciate some help.

Interesting...I am pretty sure one of mine is a 71 and the other a 72 and they are both pot metal. Sorry, I'm not sure which of those is correct. I think mine had a shorter insert side like the first picture but I don't want to steer you wrong.
