67 GT500 clutch fork?

I wanted to know if I could get a few of you to take a look at your 67 gt500clutch forks hopefully a few are still original and tell me if it is like the one in the picture that has the hole were the adjusting rod goes through the end of the arm or is it like the one that doesn't have a hole . I would also like to compare the arm and the angle as it comes out of the bellhousing if it compares to ether of the pictured 428 arms . You can see in the picture the 2 428 arms have a slightly different angle were they would come out of the bellhousing. The most obvious difference is one has a hole in the end were the adjusting rod goes through and one doesn't. I am trying to confirm a suspicion of which fork is most correct . Thank you in advance .

(from SAAC site) Shawn ,thank you very much. Your photo has answered my question. Middle arm (my pics)came off of a early 68 GT500 it has a engineering number of C8AA 7515 -A and has the flat clip riveted. The one with the hole for the adjusting arm is a C8OA 7515-A which also has the flat clip riveted . The 67 GT500 arm
(pic below)is very much like the C8OA arm that is pictured (above in first post)in its basic shape except the adjuster end is squared off instead of cut at a angle like the C8 arm . That is probably a change because of clearance concerns . The other difference is the 67 arm uses the wire clip instead of the flat clip that is riveted on. I knew the arm had to have a wire clip but have never seen one off a car to tell because it is normally stuffed up in the bellhousing. The wire clip can not be seen in the bellhousing with the dust boot on. The wire clips are a pain in the a##. I can see a C8 fork being able to be modified to look correctly on the adjuster end. This is the first time I really studied this issue because it has never come up for me until trying to replace a clutch fork on a GT500 I am restoring. I hope this thread will be informative for others about the small nuances of differences between years of Shelby's and Shelby's vs. Mustang and maybe also what can be done to modify a available part to look like a non available part. Thank you again for taking the time to respond to me in my time of need. Bob

 

The top one is a 1967 390 the middle is a early 1968 428 and the bottom one is a later 1968 428. The question was concerning 67 428 and that answer has been confirmed.
