411 Master cylinder bore specs

[Peter Grace]

Thanks everyone.

Nick - I have emailed PastParts thank you. I have also asked Bristol Cars and SLJ.
Greg and Byrn - thanks will check out the LandRover and Jaguar alternatives. This might be the fastest route.
Dorien - thanks too for your help. I think the mechanic is just trying to understand the job a bit better, it's his first time working on the car (or any Bristol I suppose)!
