69Z Brake Booster Oddity
« on: October 30, 2013, 10:53:09 PM »
I removed my nasty old painted brake booster today, and was thinking of having it rebuilt. However, I am not sure it is correct. The top tab has the number 9204 on one side, and 251 on the other. This seems to conflict with information I found here. For one, my 69Z is an 04C car. So the julian looks way off, unless it is a 68 date. Also, the DELCO MORAINE stamp is at the about the 2 or 3 O'clock position and larger letters.

Any ideas on what is going on here? Wrong booster?

1968 booster tabs had a larger size font stamp, can't remember for sure but think 68 was 1/8" high letters and some time early in the 69 model year it changed to 1/16".

Thanks Mike. I had read through that one. While my question wasn't answered there, I probably should have just revived the thread anyway, instead of starting a new one. If a mod would like to merge it, no worries here.

My original 9204 booster, dated 199, on my 09C (Sept '69) Z28 has the larger font (I believe)...

It is my understanding that the delco moraine in the 2 o'clock position is repro. The originals are upside down at the 7 o'clock.

Do 69 chevelle's have a different 4 number code.... like 9391? I know this is not a chevelle site, but I believe this came off a 69 chevelle. Terry

As I understand it, some boosters on '69 cars were made in late 68. In 1968, 251 would have been around September 8th. So before I write this booster off as a reproduction, I want to make sure. Since mine is an 04C car, is it unlikely that a September 68 booster would be original?

Can you show a closeup of the front to see the triangles? That will be easy to see if it's a reproduction nor not.

Hey Mike, take a look at the 3rd photo in the original post. You may have to scroll to the right.

 Gesh...I didn't see the scroll bar  :-[
This front cover is not a reproduction but I can't say for sure about the stamped letters. The triangles are very 'sharp' in reproductions compared to more rounded an original has as this clearly shows.
Maybe the front cover was replaced at some point with the rear cover stamping retained? This one you show looks to be in good shape and likely restored in the past.
