Need clutch help please

[Haz331]

You might want to look at Wilwood #260-6089 M/C .75 in. with 1.4" of travel. I used this setup with my push slave with no problems.

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

I just checked my AP's and they are also 1.20 but are much shorter than Girlings if that helps.

You already know the bore of the master cylinder is .750" and the outside diameter is 1.125". Which means your wall is 0.1875"

And, you know that a 1.0625" cylinder fits.

So, why not flat file .07" off the problematic side of the new clutch master cylinder leaving you with a .1175 wall; which is plenty heavy considering this is just a clutch; which is a relatively low pressure application and can tolerate the worst-case unlikely event of a cylinder failure.

In my opinion this is an extremely safe experiment, and far easier than trying to shop for a thin-wall part that may not exist.
