mid year power brake booster ID help

[Keith B.]

I located what appears to be a mid year booster. the only problem I can't find any of the numbers found in the archives on the booster. the only numbers I found were "221" on the one tab facing the front, and on the rubber boot for the M/C rod of 542867. does anyone know what I found

Kieth,
I think the 7011 is the last 4 digits of the part no. Someone will confirm.

John is correct- last four digits of the part number

Re: mid year power brake booster ID help

yes I under stand a four digit number is the part number. but this booster I am looking at DOES NOT have any four digit numbers stamped into it. only the date code

Re: mid year power brake booster ID help

did you check the backside of the tabs?

Re: mid year power brake booster ID help

The date codes of 67s were on the front and the part number on the rear of the tab. These units were specific to 67 only. The 65 and 66 were a different part number as noted above and the date was on the rear and part number on the front.

Yes cleaned off both sides of both tabs and only date stamp.
