drum brake backing plates
1969 Cale II:
This a generic question, has anybody seen, are there photos of, numbers stamped on the backing plate outsides in the small recess near adjustor hole? 2 different Fords I have done have a 4 digit number. Wonder how wide spread it might be.

If you mean the numbers that identify the backing plates then yes . I am under the impression that the numbers have to do with identification for diameter and brake pad width. However I don't know of a comprehensive listing with applications. For example I only keep track of the few unique different ones for the Shelby applications.
J_Speegle:
Agree with the identification. Two makers and two different practices as far as marking
If your are number by the brake adjusting hole then they are likely Bendix made
GinoJ:
These are from my early 67 ( but Aug 66 ) S code Convt. One Bendix, one Kelsey-Hayes.
Neither have numbers.
AJ:
I currently have 8 rear backing plates. A mixture of Bendix 317558 317559 and KH 71086 71085
Only one of them has small number, and a letter, stamped near the adjusting hole.
On a side note, i have a Bendix 323369 that appears identical to a 317558. I tried but cantdetermine its original and proper application. It functioned on my 69 Gt500 for 10 years but not its correct home. I once owned a torino with a 9 inch so maybe i cross pollinated it back when.
