Doing some work on my 66 GT350, late March SJ scheduled build. I was surprised to see the retaining ring mounting points do not have screw hole slots so you can remove them without having to remove the screws, I thought all 65-66 originals have the slots, these have been on the car at least since 1987 when I bought it.
Are these aftermarket or could they be OE?
Thanks,
Dave
