Title: 66 rear brake spring question
Post by: davez on February 11, 2024, 07:40:24 PM
My original rear brakes had the green / rusty spring which has 2 diameters.  Wider at the base.  All the replacement kits i have and have seen have this blue spring which is the same diameter throughout. Does someone know which is correct and does it matter? My k code also had the 2 diameter spring.

The double coil diameter green one is correct for 10" brakes.  Ford p/n C2OZ-2035-C.

The blue single coil diameter looks like a 6 cyl one (for 9" brakes)

Hi guys,
I have attached a page showing the rear brake parts for 65/66 GT350's. It was published in "The Marque" in the end of the seventies or beginning of the eighties. Don't know if I am correct on the name but I believe it was Roger Hodyka.

Thank You
Looking through the NPD and VCM catalogues they have listings for the 66 350 but the photos online and what I received were the single diameter spring. I'll reuse my old springs.

Dave, that is what I have done as well.

as usual, i bought several kits from original supplier and found that only one spring was not availible, think it was the black one that is heat treated. got a match, but wrong color, stripped paint, color matched dip painted as original. lso color matched and painted the others. btw, still have original segment shoes and the adjuster plugs in backer plate

TX Swede,
 I will claim authorship for that article in the Marque!
I was working at a Ford dealer in Farmington MI at the time and found a customer we had was a K/H engineer.
So I questioned him on the unique Shelby brake hardware, he is the one who told me the springs were functionally the same as the RPO Ford hardware, the difference was the springs were made to tolerate higher temps without loss of performance. "hi temp springs"

regards,

Hi Bob,
I was mistaken. The article was in The Shelby American, Sept-Oct 1979, Volume 4 Nuber 5, Page 9.
It was sent to Jeff Burgy by Roger Hodyka
