I am having trouble with the stroke of my clutch and while searching the forum I found this thread. I know how to fix the problem, but I am having trouble finding a suitable master cylinder. The one that I have is 5/8" remote reservoir girling P5060, but I need to replace it with a 3/4" bore like a Wilwood #260-6089. The problem I have is that the distance between the brake power booster and the clutch master cylinder is about the thickness of a piece of paper. This means I need a master cylinder that has an outer diameter of the main body of 1 1/16"(27mm). The PBR master cylinders that are available in Australia and which are similar to the Wilwood have an outer dia of 1 1/8" which is to big.
If someone who uses the Wilwood #260-6089 could tell me the outer diameter of the main body please or does anyone know another brand of a remote reservoir 3/4" master cylinder that would fit.
If all else fails I can use the larger diameter master cylinder and space it out, but that makes the pushrod longer which could be another potential problem.

Thanks
