They are only a 6" single diaphragm and IMHO, by today's standards inadequate (even by 1970's Aussie standards too), it is why in 1975 I fitted an 8" PBR booster from a Holden to my SIIa 109.
Cookey's mod is an improvement again because of the dual diaphragm, with the benefit of the OEM master cylinder.

its your choice, but my Defender with the same master cylinder as the late SIII runs an OEM booster which is either 9" or 10". So I guess that is another option.
My old servo has now been overhauled by Hydroboost http://www.hydroboost.com.au/
I had the option of linishing the outside to get a better finish (mine had a lot of rust pits) but decided against because it's not going to be a trailer queen.
Ended up having studs welded back in and a new pushrod made. Apparently it is the worst condition servo Terry has repaired.
Genuine parts used and cheaper than a pattern servo

I have no association with Hydroboost other than as a satisfied customer.

Anybody have a link to write-up on the booster conversion on an early series 2A?
Also, am I correct to say the Series 2A used a shared reservoir between clutch and brake? Isn't that quite stupid? What option there for splitting that up?
If you look inside the reservoir it is divided.Quote:

Single fill point but priority given to the brakes. Quite clever really.

Ah the plot thickens. No wonder I still had clutch when the RR slave cylinder self destructed on the way home after buying She Devil.Quote:

Hi Colin, have you been happy with the servo that Hydroboost did for you?Quote:

Hydroboost make parts and get the diaphragms made and know what they are doing. I've since seen a few negative comments about the aftermarket servos.
