Re: Reverse Light hole in firewall
I just check my 68 AIM, and it shows the hole in the same place. If you have an AIM, the hole is shown on UPC 0 sheet A 8.5 (up front, 10 pages in or so). That is location 3C for RPO M20, and the AIM says to drill a .920/.940 diameter hole at existing dimple. So, if you can find the dimple, you just need a 15/16" drill bit (or more likely hole saw).
