What would be the numbers correct master for a 69 442 drum brake car?
Could they be found on other GM models?
Core value?

Thanks

The casting number for the 1969 drum brake master is 5460465. The two letter code stamped on the top front is "CT".
The "CT" drum master was widely used on GM cars. The "CT" master was used on all Olds "A" bodies from 1968-1972.
I would think at least $50 for core value.

Thanks for the reply
I now know what I looking for.
I still don’t know if I will race with a rebuilt one but definitely use it for showing once the car is completed.

Hi Al
The car is not yet in the new shop yet as the shop is still under construction. I'm in the parts acquisition phase, as I'm still trying to move the car forward.
It will be years before the car is done as this is a complete restoration using original and period correct day two parts.
Sourcing and researching the correct parts has been educational. Big thank you to Classic Oldsmobile forum members.

in addition, CT is correct for manual or power drums. I've seen them both with and without bleeders

Thanks for the reply
Is one more sought after than the other as in with or with out bleeders?
Would a factory replacement be void of the CT as in blank no markings?

Having the "CT" stamp is certainly more desirable.
In later years Masters would have variations such as no bleeders but a "CT" stamp and vice versa.
They eventually made the masters with no bleeders or stamps.
