I'm not sure if this is the correct location for this question but it seems as good as any...
I recently replaced one of the side windows on my 68GT. While doing that I had intended to replace the screws on the window bar since they were a little warn. However, they do not match up to any normal hardware I could find at ACE, Lowes, HD or even the local specialty fastener shop. They appear to be 3/8" & 1/2" #6 sheet metal screws with a flat tip and 18 tpi.
Anyone know what these screws specs really are and where I might find replacements?
