Headlight cover bolt size?

[joe]

Anyone have any info on the size of bolts/screws typically used for the headlight covers? I'm looking at installing threaded nuts into the fiberglass and then bolting the covers down.

SPF uses a small stainless screw. Don't know the size. Not sure you need bolts for these. They are super lightweight pieces.

Mine are probably going on and off during fitting and bodywork more that a Superformance car. I don’t want to rely on the fiberglass holding up to screws.

indeed, this is the way to go on the fibreglass end. Use m4 aluminium (aluminum if in the US ;-)) countersunk anodised Allen head screws. For the Lexan part: taper the bore holes with a suitable drill bit, wood bits will do for boring the straight sections...
