Clutch master cylinder rebuild kit

[AMC of Houston]

Well, that kinda sucks!   Any AMC part numbers on it anywhere?   But then it may not even be an AMC part!  Bummer.

No the only things on it are the part number I posted earlier the name Girling and made in UK. So my guess is it's something AMC sourced from them instead of making it themselves.

Well, I bought the Crown kit from Summit Racing that AMC of Houston mentioned and compared it to the one from RockAuto and they seem identical.  I then took them both to a different transmission shop and asked them to rebuild my clutch cylinder.

I got a call the next day; it turns out that neither of the kits will fit my master cylinder.  He had my cylinder taken apart on the bench and showed me the original seals vs. the ones in the kits, and both of the kits were visibly smaller in diameter.  I don't understand what's going on, unless some previous owner replaced my cylinder with a non-standard one.  He is now trying to look at other random rebuild kits to see if he can find one that will fit.  The whole situation is pretty discouraging.  This may be the issue that makes me just walk away from my Eagle.

If anyone is looking at this thread because they are trying to rebuild their clutch master cylinders, all I can tell you is that neither the RockAuto or Crown kit will fit my 1984 5-speed Eagle.

I checked my parts books; and there was a boatload of different cylinders over the years:

J5359822 - '80 with GM 4-cyl (MC & reservoir one-piece casting)
J3236757 - '80-'83 with GM 4-cyl (MC & reservoir are two separate service parts)
J3238951 - '80-'81 6-cyl (prior to engine code 011C03)
J3238493 - '81-'83 6-cyl (after engine code 011C03), '84-up GM 4-cyl, and '83-up with AMC 4-cyl
J3238951 - '84-up 6-cyl

Repair kits listed are:
J8132781 - '80-'83 with GM 4-cyl
8983500677 (or 83500677) - '84-up with GM 4-cyl, and '83-up with AMC 4-cyl
J8132911 - '80-up with 6-cyl

Probably doesn't help, I know.

Rock auto will ship to Colorado just not to home rule cities.  I rent a post box in superior and they deliver there no problem.

So find someone outside of a home rule city or a post box you can rent outside of one and that should do you!

Good luck!

I finally heard from the people from the Girling website and they said that they don't have any kind of a repair kit for the master cylinder I have and I also just recently found out that it's for a 4 cylinder car not a straight six not sure if that makes a difference but I think it might.

I'm updating this thread with info I've figured out (the hard way) while trying to find a rebuild kit for my 6-cylinder with a 5-speed.

Both the RockAuto kit (Lucas SP5903) and the Crown kit from Summit Racing are for the 4-cylinder car only.  They fit a 3/4" bore master cylinder; the 6-cylinder cars use a larger bore. 

I have been completely unable to find a kit for the 6-cyl MC.

I sure do. You can get a rebuld kit from Blaser Auto. They have them in stock. Blaser Auto specializes in AMC, Nash and Rambler.

Y'all might wanna check THIS post if it helps anything. Something I found on a spacebook Studebaker page. I don't recall, I THINK this guy was looking for a brake master cyl. kit, but due to the age (& the fact it was a Studebaker) folks were suggesting rebuild places. Don't know if this helps or not, just something I saw.
