How to connect Jeep clutch master cylinder to Chevy slave?

My Jeep is a 1995 YJ. It had an AX5 with an external slave. Now it has an SM465 with external slave. How do I connect my Jeep's master cylinder to a Chevy slave cylinder? I know Novak sells a fitting that will enable me to use any hardline, but I was hoping I could reuse the fitting and line I already have to save a couple bucks.

Anyone who has done it could I get some ideas and maybe pictures?

I'm trying to do this myself as well. I have a Getrag 5 speed with an internal slave that I'm getting ready to hook up to my Jeep master cylinder. Did you have any luck or did you have to go with a Chevy master cylinder?

Its easy go to Advance adapters and get the fitting that adapts the Jeeps master to a regular brake line flare and run regular brake line.

The AA fitting is not a regular brake line flare. It is a -3AN. You could get another fitting to go from -3AN to the standard threaded brake flare.

Here is what I did. This is on a 95 YJ with external slave I think the internal master cylinder is similar.

I used an 1/8" punch to drive out the roll pin that holds the line into the master cylinder. I then cut off the plastic hose and hack sawed off the hose barb off the fitting.



I then drilled and tapped the fitting for 1/8" pipe thread.



Then I threaded in a 1/8" pipe thread to 3/16" flare adapter from my local hardware store. Check to make sure that the fitting does not screw in so far as to block the passage. If it does cut it a little shorter.




I then reinstalled the fitting on the master cylinder and ran 3/16 brake hard line down to next to the slave cylinder on the body. Then I used a rear center brake hose from a 83 Caddy Eldorado (3/16" flare both ends about 8" long) to form a flex line to the a short piece of hard line into the slave cylinder. In my case it was a Jeep CJ slave but I think the chevys have the same threads.

In my case the YJ master did not move enough fluid for the CJ slave and I had to change out for a CJ master, but other wise it worked great. In your case I think the YJ master will move enough fluid as the chevys used a smaller slave then the CJ's.

Great info! Thanks for posting. Before reading this - I was thinking compression fitting on the short piece of plastic - and not feeling real good about it.
