9" vs 10" rear drum brake internals?

[Trevor B]

Hi All,

Back to working on Mopars after a long hiatus! I'm building a 1971 Duster.
Duster came with SBP 9" drums on a 7.25" open diff and I decided to swap out for the much better rear end that came with my 1968 slant six Barracuda: a factory 7.25" with Suregrip and 10" drums! I've been holding onto this for many years (ever since I upgraded the Barracuda to 8.25" and put a 360 in it).

Anyway, I lost or gave away the internals from the 1968 brakes - it's just backing plates, axles, and drums.

So: will the 9"parts work for the 10"?
- strut + spring
- adjuster lever
- cable guide/overload spring
- parking brake lever
- etc.

Thanks in advance!

No such luck ! I don't think they will swap.

Nothing at all will swap except the parking brake cables...

Okay - thanks for the info. Saves me the hassle of cleaning up those filthy parts!

Btw, your 68 brakes will have a cable for the adjuster vs 69 up that has a spring in the adjuster cable. Also the misc hardware need to match the adjuster cable. 69 up or 68 and down
