66 rear brake spring question
« 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.
