Rivets

[Christopher Ball <triumph@io.org>]

Do any of you, perhaps the Lotus 7 bunch, know what the heirarchy of
rivets is ?  There's the humble pop version, and then there's the two 
sided kind that we used at de Havilland on the aircraft. Is there a 
"qaulity" version for non-stressed car work, that is superior to the 
pops? I have not seen anything else for sale here in Ontario. 
Maybe I'm just being unfair to the pop rivets? Several brackets on the 
TR3 are held down with them !

thanks for the help.
