Vent window rivet tool
I’m so glad to of have found this info on a search.
I just ordered the tool you located, I’ll alter as needed to fit as you had.
Some of my holes became enlarged and I use oversized pop rivets , only used on tabs on divider shaft.
I too have fallen pray to the rivet repair kit ,that tool sucks, yea try holding it ,the rivet , hammer and keeping it aligned while
not bending the frame.
Thanks,Bakydnutbstr
