Thank you David for the templates.
Lense isn’t centered just tossed in there.
here is a tech tip. Use an old crappy collar from an Appleton spotlight, slightly oversized drill bit, some cutting fluid, drill STRAIGHT through the collar (or use a lathe), screw it together and you have an Appleton drill guide to install your spotlights with. It’ll take a 1/2″ and not hit the threads. Build the car yourself at 3am.
