My inventory sheet says the 97245-S35 (Wittek #9) requires 6 for my application I have 5 of them with one damaged strap.
My notes are as follows:
97240-S(x), 13/16 grip, Witek no 5 - verified
97241-S(x), 7/8 grip, Witek no 6 - assumed
97242-S(x), 15/16 grip, Witek no 7 - verified
97243-S(x), 1.0 grip, Witek no 8 - assumed, not used on Mustang
97244-S(x), 1 1/16 grip, Witek no 9 - assumed
97245-S(x), 1 1/8 grip, Witek no 10 - assumed
When I look at the codes for S35 in AMK book, it isn't there.
I use the "AMK Guide To Ford Fasteners, 1955-73" as a source. It say -S35 is a dull yellow zinc finish.
I notice the Assembly Manual did not note the exact finish on 97289 since they left the finish code off, I also see in the spreadsheet you put the "(35)" (in parenthesis).
I found no direct finish information so I put the -S35 code in parenthesis as a flag that it is assumed, and not verified.
It looks like all the 67 V8 engines use a -S35, dull gold zinc, finish. There is no disagreement there.
What I would like is your source for Witek side code to Ford part number.
Note: The 67 Engine Assembly Manual shows a -S8, clear zinc, finish used on 67 I6 engines.
