also where does every CSOB go to purchase them?

your CSOB friend,
Roger

autopartswarehouse has the '74-'77 2.7 liter 911 brake master cylinder
for $231.00.....

Well Don't buy it from them. I seem to recall 19mm M/C going for around 100 bucks.
If I could EVER decide what I was going to do with my brakes. I know I got a near new one. Make me an offer I guess.

now i'm finding differences in years..
'65-'67 is one kind.
'69 and '69 are different.

i believe you want 69 and later.....

pelican describes the difference. i want to say single vs dual circuit

SWB 911s have a single circuit system. So 68 and earlier are out.

cool, so im not suffering from CRS disease

1969 911 master cylinder
autopartswarehouse.com $239.00
drivewire.com $222.00

Pelican Parts has the 19 mm MC for $208.

Also appears to indicate the part number is 911.355.012.02, but I can't confirm or deny that part number.

I paid $200 for one a couple of weeks ago. I got it through a local shop (downtown Sacramento).

just got back from seeing John over at EASY in Emeryville.

We dug through a couple of 911's and found a newly installed 19mm MC in one of them.

$$$$ 40.00 $$$$

picked up my front suspension braces to. $5 each. <big time smilie>

God is great, God is good. Let me thank him for my mood. Oh, is that too religious???? LOL
