69 Z28 Power Booster & Master Cylinder Assy
« on: December 15, 2007, 11:36:03 PM »
I need advice.  I believe I have the original booster (but someone painted it gold) and an odd ball master cylinder. I was considering purchasing a new reproduction system, but there are literally dozens on ebay.  Some claim to use original boosters and repo master cylinders, while others claim the master cylinder is original.  It would be easier for me to buy a completed assy rather then trying go through the headach of plating etc.  I'm sure there are threads on this, so if someone can give me advise or direct me to the link. Any help will be much appreciated.

Depends on what you're building.  Are you trying to restore or keep your car original?  Then you'll want to do it right, get the right parts, dates etc.  If not, then whatever works for you.  I think I'm probably not alone in saying I wasted more time and money by not researching before I did something, and having to do it over to make it right.

Look on the tab pointing up on the booster. Should have the numbers 9204 on one side and a julian date code on the other. If it is original send it to my firend, Steve Gregori here in Fresno County. He does alot of them and they turn out nice. ;)

Contact Jerry MacNeish, he plates them and does a great job.  He has done several for our Camaro Club.

I appreciate everybodys advice.  I'll remove the booster and make sure it's legit, then send to JM.  Still have the MC issue where guys are selling on eBay as original.  I'm trying to get the car correct as possible, but it will never be a ponts car becuase it does not have the correct VIN on the DZ motor.  I'm still open for suggestions.

YOU DONT HAVE TO REMOVE THE BOOSTER. THE 9204 IS EASILY READ WITH A MIRROR AS IT FACES THE FIREWALL. THE JULIAN DATE FACES FORWARD AND IS 1 THROUGH 365. EASY TO FIGURE OUT BY THE PRODUCTION DATE.
GOOD LUCK. PERSONALLY I WOULD RATHER HAVE AN ORIGINAL REBUILT MASTER THAN A REPRO.

Are you looking for a 5468309 US master?  I would think those are fairly common.  I found a correct one for my 68 Z (which is a different one) and saw lots of 309 US mcs on e-scam not too long ago.  Cheap compared to the rest of the things I've bought.

I just bought what is supposed to be an original Delco rebuilt 309 on eBay.  I believe my booster is correct as I can see the 9204 behind the cheap gold spray paint.  I plan to send it to Mr. MacNeish.  Now any resource and the proportioning valve or what needed to restore?

Have JM replate the round metering valve bracket as well as the booster. There is a place in the LA area called Karp's Brkae. The can rebuild the metering valve if JM can not.

Does the date always face forward and the booster number always face to the rear?

Just had CHP rebuilt my proportioning valve and replate my caliper brackets and they looked great.
