1969 dart tail light bezel screws

I tried to find some with no luck. I had the hardware vendor where I work look for some and they found a place that would make them but I didn't want to buy 1000 for the few I needed. I know they have a smaller counter sunk head for the thread size they are. #8 with a #6 sized head comes to mind. What I did was helicoil my buckets and use the smaller screw. PM me if you can't source and I'll get you exact details of what I did.
