What do you do when missing screws?

I would have mentioned the hardware store too except for the fact thatt the OP mentioned that he didn't have the fasteners in the first place. The reason I mentioned the companies above is that they offer the correct screws for a particular application,'sometimes maddeningly hard to find at the hardware store, especially with the hundreds of different screws on these cars!!

Try finding those shoulder screws with the smaller heads for dash bezels,'or the phosphate coated screws in black for blacked out headlight bezels and such!

Do they cost a little more through the above companies??... sure, but you're getting the correct screws.'if no example or parts car is a a available, my suggestion is an easy way to identify which fasteners you need!
