Are brake master cylinders date coded?
My '66 appears to have the wrong brake master cylinder, as follows:
http://i54.tinypic.com/nyi542.jpg I understand that the '66 had a master cylinder that was unique to two years of production, I believe '65 and '66. Is this correct? The correct part looks like this: http://i55.tinypic.com/10clwgj.png I am in no particular hurry to return this part to original but intend to be on the look out for the correct part. In doing so, I need to know whether the brake master cylinder for a '66 is date coded. BTW. My car's build date is October 8, 1965 |
The lower photo shows the correct casting style for '65-'66 model year. The upper photo with the bails & one-piece cap is '67 & later style.

Thanks for confirming that. Are the castings for the '65-'66 model year dated? I don't want to go to the great expense of getting the proper part ($800 - $1,000) and not have the proper date. Are these castings dated?
The original casting number of the 65-66 power MCs is 5467084, and is found cast into the side of the MC. More important than the date on these MCs, is the brake line diameter. These master cylinders came in two versions. The first design one was used for part of 65, and used a 3/16" line. The second design MC, was used for the later part of 65, and all of 66. The later one uses 1/4" lines. There are no markings on the MCs to differentiate which line size the master cylinder is, so you have to be careful to make sure you get the 1/4" line one. If you can find a good useable 65-66 power MC for $800-$1,000, grab it. The re-builders pay $1,000 for cores. The 65-66 PB MC's always need to be sleeved. A stainless steel sleeved rebuilt, without a core, will set you back about $1,500. There is a repro coming, but I'm not sure if it's available yet. I think the price is supposed to be around $350? |

Some MCs do have a date stamped on the flange, were they bolt to the booster. I don't recall if the 65-66 power MCs are dated though.

Master cylinder dates
The castings are Julian dated. The "date" is visable from the output line side of the housing. The attached show a "98" for example. The year is dictated by the size of the line.
