Julian Date For 9204 Booster
 

I have a 1969 Nova built 05C, the 3rd week of May, in Willow Run Michigan, and I need to know what the best Julian calendar date would be for a 9204 Brake Booster. What is the correct back figure, as far as how far back from the build code, would be the correct Julian Calendar Date, for the 9204 booster for this car? Would I be looking for a 99 or a 121 Julian Calendar Date, or something further back, or something closer to the Build Code of the 05C? I just need the rule of thumb or what is correct so I can find what I need for this car. Thanks everyone!

For reference, my 05A Z/28 has a 120 dated 9204.

Thank you so kindly!

My 02B camaro delivered Feb 13 has a booster dated 39. It is super close to the build date.

Have an 02d w a 042 booster

Thanks everyone for the input on this booster date and build date info!

so is it a known fact that 69 Nova's had 9204's same as 69 camaro? I tried to find this info out couple years back when I had a Nova

Yes that is a known fact. I've had 4 69 Nova's that each one had the 9204 Booster. Same thing as the Big Block having the 13/16 sway bar verses the small block 11/16 sway bar, the Big Block heater cores, the Big Block inner heater box, the frame mounts, coil springs, and so forth. Pretty much everything was the same on the subframe and firewall for 69 Camaro and Nova.

thanks I searched Novas.net and Steves novasite and couldnt get confirmation of that
I dont think that all has 13/16 sway bar did they?

You are correct on the 13/16 sway bar. Only the Big Block cars would have came with that option. The small block v-8 came with a 11/16 sway bar. I have seen where most 6 cylinder cars did NOT have a sway bar, yet I have seen a couple where they did have a 11/16 sway bar. I've yet to confirm any of that but that's what I have witnessed over the years. Also, I might add, that there were some cars with power brakes that did NOT come with the 9204 booster. The majority of the 9204 boosters that I have found were for power disc brake hi performance cars and Big Block applications. Again, this is what I've verified or witnessed over the years.

A 69 Nova or Camaro with power disc brakes would have the 9204 booster...I don't believe the engine size [small block vs. big block] mattered, both used the 9204.
