Default slave cylinder piston seals

Does anyone know if a set of rubber seals is available for the 1 1/16" bore. Possibly from other vehicles?

According to what I remember the C4 system is shared with the S-10 series. I think Bill told me that....but don't qoute me...check it out.

Also FWIW the cast slave cylinder from Fedral-Mogal uses a different piston seal. It is visibly larger in shoulder area and has no micro-ridges to tear up. The shape generally looks more like a mushroom. The piston and the return spring are exactly the same as the DOM versions from GM and the after market, like wagner & raybestos.

I used the piston/spring/seal assembly from a F-M cast unit & transplanted it into the best DOM slave body I had in my inventory and so far so good!

Here's the info from my bill: Brand: MWG Our Part No.: F120165.

I tried to get rebuild kits but no one seems to have them, not GM or aftermarket.

Okay Brandon this is convoluted, so humor me a bit!

I fell victum to the Q/C issues w/ the DOM type slaves. Out of desperation I went to autopartswarehouse.com to see what they had. I was using dealer parts, then Rockauto.com parts....no joy with any of those. There is alot more to the Q/C issue than just the seal reversal.

Anyway @ autopartswarehouse.com they had a cast type slave (had is the operative word, it's no longer listed now) by Federal-Mogul. I e-mailed the "on-line" help and they said it was not a TRW unit. So I figured why not try one.

On my bill the "shipping point" is listed as:
Allentown Distribution Center
Federal-Mogul Corp.
6736 Tilgman Street
Allentown, PA 18106

The P/N I listed, F120165, I think is a F-M P/N. My bill further states that from the F-M dist. center the slave was sold toI assume that this is autopartswarehouse.com???)
Middle Atlantic Warehouse
8980 East 33rd street
Indianapolis, IN 46226-6530

I assume that on my bill where it says "our brand" = MWG, that is autopartswarehouse.com brand???

The only reservation I had about using the F-M slave was that as a cast unit the mounting flange looked to be too thick and looked like my retainer nuts wouldn't get a good enough bite on the studs. That's whay I transplanted the guts from the F-M slave into a DOM body. Obviously that's when I saw the difference between F-M's seal and TRW's.

Only thing I can suggest is call F-M directly and try the P/N I listed or try by application. Mine is still working after about 5K miles. Oh, forgot this, the rebuild kits are NLA from GM. They used to be listed in 06 but when I tried to buy they came back NLA.


Tom
Sorry about the convoluted write up!
