Brake Boosters and Master Cylinders

[CamarosRus]

I have heard only a 9204 Booster being correct for 69 Camaros. This is stamped # on firewall side of TOP tab where two booster halves mate together???.... is # on the front the date. Are there ANY other boosters from other Nova, Camaros that are cosmetically the same as 9204????
My ORIGINAL July(07E) 1970 Z-28 booster has a 9204 stamped on it....This was end of 70 Camaro run.....How could it have a "leftover" 69 Booster on it.....so apparently 70 Camaros used the SAME booster as 69??????
And,also please comment on the 309 and 346 Boosters and the useage???????please Email your post to Chuck [email protected]

CamarosRus,
I checked my original booster for my August 69 built 1970 Nova. The number on the back of the tab is the same and it is 9204. The number on the front of my tab is 205. I don't know what these numbers mean. Maybe somebody else here can educate us?

69 Novas use 9204's. The other number on the tab is a Julian date. 205 is the 205th day in your case. The great part about the boosters is the important info is on the back half. If the face is pitted it can be changed. Normally the back half stays crisp since it is shielded from brake fluid and other contaminents...BKH
