Thanks Steve! You were the one 11E car that I mentioned above.
Great overall pic that shows how that master differs!

Charlie,
Thanks for the detail pics.

We still should have some more data - two solid datapoints does not make bulletproof data. Smiley
I've started to edit the page - I'm thinking about the pics right now....

Hey kurt as soon as i get the other info about this new Nov. car i will submit info.  I just remember i got another pic with this setup but your site can't handle the size. This is from a different car too.  And if there is another angle you want let me no. There is another casting mark on the back side that resembles the size of a stick of gum. The side between the engine and M/C.

If it helps my 4k- car built 05D has a master cylinder 5459467 (the 6 looks like a S), also cast is 1" with a cast date of 10 D 7. I know of another 67 4k- built in July with manual disk also, don't know his casting numbers though. Grin

I honestly believe that chevy recomended this manual disc for 4K cars sometime during production.  I have owned my car for 23 years and out of all the camaro's i have seen over the years the only ones i have ever seen were 4K cars with this setup.  I am talking about the percentage of 4K cars compared to all other camaro's.  Z28 cars were not involved with this either.  So the research is not there in this car.  I am thinking if someone special ordered a car then that was done . But normal production 4K car i think came with this setup.(option)  The first car mentioned with this is above with a sb engine. First i ever heard of. 
YENKOL88 are you saying that your jullian date is 10 ?

Looking at the post i am on on camaro.net  there is a guy with 4K car O5D date and has the exact numbers as you do.
We all need to stay with this until CRG changes the info on it's site.  This is correct for all camaro people!!!
Anybody else with info please help.

Looks like YenkoL88 and 06A are the same person. That's why the #'s are the same.
Welcome onboard!


Charlie,
We've seen the manual discs on everything from L6 cars to 327's to SS's. Most are on L48's (SS350) (almost a magnitude more than on L78's). Which makes sense, there's a lot more L48's than there are L78's.

We all need to stay with this until CRG changes the info on it's site.  This is correct for all camaro people!!!
Umm, you sound like you are trying to fight city hall. We're not like that here.
Did you read my post on the 8th?

SORRY . I did not no YENKOL88 was the the same guy but i am trying to get people going on this to help "all' of us camaro guys out.  I am sorry if i pushed

Yep got a couple of cars, but this one has the AD stamped manual cylinder, A and D look stamped individually, and bounced cuz you can faintly see the rehits on the A. I could send a digital pic as we are cleaning it all up, the date looks like 10 D 7.......I assume april 10, 1967 for a late May car. Maybe Joe can chime in on his manual disk 4k- also. I think manual disk is just a regular option that saved weight from a power set up for drag racing and at the same time stopped the car better than drums when racing. No big deal really. I heard a number of something like 200+ 67s getting the option.

The one on my July car has 318 for jullian date.  The other M/C i have has 87 for jullian date.  I would say that the D7 does not mean April.  I think yours might be Jan. 10 . Everyone i have seen has the D7 on them.  I am thinking your way on the disc usage for these cars, also thinking the lack of vacumme when racing.

Thanks for the decode on the date. Are any stamped differently if they came w/ the metallic pads?

There was a whole lot more than 200, seeing that the database has more than 200 of them in it! Over 100 of those have docs. That 200 number is for J65, http://www.camaros.org/suspen.shtml#Brakes.

Not a total SWAG, but looking only at documented ones versus the rest of the documented population came out to a little more than 3%, so maybe 3000-6000?

Buddy,
Thanks for the data!

L88,
Nope, metallic pads wouldn't have affected the codes. But J56 was only available on Z28's.

Charley,
There's a difference between having data on the vehicle and having actual data on components. I personally don't watch 67's that much, never noticed the difference. Smiley
If you don't know what I mean when I post something, just ask.

I've finished the editing of the page (and did a bunch of other changes). Should be online soon.

I would say that the D7 does not mean April. 

The D7 is a foundry pattern number, not a date.

I updated http://www.camaros.org/suspen.shtml#Brakecomp.
It has the the updated master cyl casting # for manual disc and Steve's pic. I also added info on the rear proportioning valve, steering info, and spring application data on that page.
