My latest detailing project on my SVO is the front suspension. While refurbishing the front sway bar, I noticed that my end links didn't match what I had seen on other cars. Apparently they had been replaced with after market parts somewhere along the line (prior to my ownership). Using Daniel Carpenter's low mileage SVO as reference, you can see that the hardware is phosphated, the nut is zinc plated, and the bushings are turquoise. The original Ford kits listed in the '86 Parts Catalog, E5ZZ-5A486-A, have long been obsolete.
The Ford service replacements listed for an '86 SVO (E6ZZ-5A486-A), are not concours correct. You will notice that the hardware no longer uses a metal sleeve, but rather a crimp in the bolt and the nut is now attached to a washer on both ends.
The Moog aftermarket kits are a little closer to oem, but the hardware and bushings are not concours correct. You could reuse the metal sleeve, refinish it, but that is about it.
Referencing the 1986 Ford Parts Catalog and David LaRoque's SVO book, I came up with the following list of parts required to create a concours correct end lnk.
Of course the other option is to refinish your oem hardware, but typically the bolts corrode under the bushings and need to be replaced.
Talking with Kendal Coker on the subject, it appears that the '84 SVO came with black rubber bushings rather than the turquoise colored bushings used in late '85 and '86. We are not sure when the actual change occured. I have attached a picture of an oem end link that came from one of Kendal's cars (minus the black bushings). I have an assumption of what the Ford part number for the '84 kit is, but it is also long obsolete.
The turquoise colored bushings are used into the 90's (F1ZC), but I have not found a source for these.
Hope this helps.
