I think they went out of business a while back.

Their site seems to be just a framework

I think in various threads they mentioned to check with KarTek or Mckenzie.

That said, if you cannot find the seals...post what the ID of the seal groove on the slave is, the piston diameter and the seal width of the groove in the piston. I may be able to put you on to EPDM U-cups that fit.

Measure the same on the master cylinder. Ray

FWIW, look into replacing the SACO MC with a Wilwood (and modify the mount accordingly). If you're at the point where the SACO MC needs a rebuild, the bore of the MC is cooked, and simply rebuilding it is only borrowing you some time.

I had my SACO master cylinder rebuilt by a hydraulics shop in Charleston, SC and though I had confidence in the folks doing the work, the rebuild was only good for a few hundred miles of city driving and then it failed.

As above would suggest switching to a proper clutch hydraulic master. The bore of the SACO is 0.75" and that's a common replacement size for masters.

Probably spot on. IIRC SACO stuff has aluminum cylinders. While the pistons in most MC should never be touching and wearing on the bores, the SACO MC alignment is a little odd compared to factory stuff.

Wildwood should be better. I have never been that impressed by the SACO designs. Ray
