Master Cylinder stamped SA
« on: May 17, 2016, 03:10:50 AM »
My 10-1-69 P&A has a listing for 67 Chevelle w/Disc Brakes, 67-69 Pass. Camaro w/Disc Brakes ....5469489  (11/8" dia. cyl.) (stamped SA).
I know the 67-68 MC's are stamped WT but was this the early 69 MC before it was  updated to the 5463751 and 309 casting stamped US?

Bob from the wording in the CRG Chassis section brake article:
Quote
1967 and 1968 power disc brake cars used the 5460346 master cylinder. Early 1969 disc brake cars also used the 5460346 master cylinder (for about a month or so of production) with later 69 cars using the 5468309 casting.
I took that to mean that the early 69 cars also used the 'WT' stamped master until the switch to 309/US, but maybe that's not a correct interpretation?

Here is a 69 Camaro LA 09D 68 with the 309 master.

Nope, that's not what it says. It only mentions casting numbers.
The application codes were by model year.

Thanks Kurt. So did the early-built cars get a 346 master stamped 'US'?

Yes, that why I wrote: The application codes were by model year.
