Master Cylinder Recommendation

I am in the middle of a front disc brake swap on a GPW and was wondering what dual reservoir master cylinder people have gone with? With everything thing else I need to do on this ease of install is a huge plus.

Are you keeping it mounted in the stock location on the frame or doing a hanging pedal/firewall mount ?

Frame mount.
One of the great achievements of science has been, if not to make it impossible for intelligent people to be religious, then at least to make it possible for them not to be religious. We should not retreat from this accomplishment.

Salesmen and women. God sells to the ignorant.

Different rig but I used a late 80's Cherokee. It is kinda big and may not work for you.

I used a wilwood dual MC that mounts to the frame, and has remote reservoirs that mount higher up on the firewall. Manual, no power assist.

It was pretty easy to install, but at the time there was no motor/driveline/axles in place, and no fenders or front body, so access was extremely easy.

I kept the factory clutch/brake pedal, and running disk brakes. At the time of install the rear was drum, it's now disk. If I remember correctly there was a part that threads in to get the pressure correct for the rear disk, when I later changed the rear over to an axle that had disks.

I THINK this is the one I used, it looks identical from what I can remember:
If it ain't a flat-fender, it ain't much.

I'll second manual wilwood. (although I have never used a dual MC, always just dual masters.)

If you are going to hanging pedals, use '79 CJ7 for the MC. If you are lucky enough to find a 7 with the pedal assembly, it can be adapted into a flatty. It's some work, but I have done it with good results. The major plus is the ability to go to a hydraulic clutch at the same time.
