I ordered some allenhead set screws from Classic Parts awhile back and so far so good. Been holding tight for a couples months now.
Will try the aluminum foil trick next (if needed) then advance to the drill through phase (to stick a fork in it, so to speak) if it gets that far grin
Amazing how something thats seemingly so minor can become a major irratent ain't it. Nothing like the sound of a door or window handle falling to the floor board after a bump grin
