Doctor Diff Master Cylinder

I bought a Doctor Diff aluminum master cylinder some time ago and now it's getting wore out and was wondering if anyone knows of a place I could buy some new pressure seals?
I emailed Doctor Diff but got no reply and tried to start a conversion with him on here but his box is full.
Or do I just but a new master cylinder because there not rebuildable?



Great supplier!

I'd be very surprised if you didn't hear from him shortly.

He's a very reputable guy.
