Early 1969 Camaro Master Cylinder 5460346 or 5468309
 

I have an early build 1969 Camaro 09B where everything is dated between last week of July to first week of Sept 1968. I am missing the original master cylinder which should be a 5468309 but I read in the CRG site my car could have had a 5460346 master cylinder. I talked to Mike Gibbons and he feels my car should be a 5468309. A date around 230 would be perfect. I have a 309 master dated 133 for trade if needed. I welcome any feedback, thanks. Dave.
