Sam they are perfect!! The larger hole below the screw I have installed is for the next size up screw (pictured, Greg's F-86 canopy screws) the smaller screws are for the glass retainment and the larger ones are to hold the frame to the fuselage. The only problem I have now is seeing the darn things[sm=spinnyeyes.gif]
Bill we get our screws from the manufacturer but I think they go by the name Grobet. Oh by the way, I am on your build site all the time and do we have to talk, I have the perfect engines for your Lightning
