Topic: Ignition switch ground strap bracket (screw type ?)

[jwc66k]

If I can impose on a forum member or two with a 1967 or 1968 Mustang to do a "sanity check" on that screw in question. It's a simple request, take a 1/4 inch hex socket and a 5/16 inch hex socket and see what size drive the screw that retains the ignition switch retainer is. It's located to the right of the steering column under the dash and directly under the ignition switch. That measurement will give a "clue" as to the screw size.
Thanks,
Jim

Never seen 67 or 68 from any of 3 plants with 5/16 hex. Different head markings but always 1/4

Tim,
Thanks. That hex size lends credence to the screw being a size number 8.

, I have seen CF, one with concentric circles and another with a triangle in the middle. The CF is by far the most common.

Thanks to all for the information!
Os there is a picture of the CF with triangle in the middle please?

Believe (which matches what I've seen) there are three versions he is referring to

Center head markings of these screws for different years, plants and applications '

1- CF
2- Concentric circles
3- Triangle

There are similar screws with Diamonds but not going to add that in to create confusion
