1964 4wd 3/4t - Power brake upgrade

[Skywalker1210]

Hey there,

I am looking into upgrading the brakes on my 64 K20, mainly the power brake booster and master cylinder.

I tried to locate the parts with the usual suspects (LMC, etc.), but so far, no one knew what I needed. All the sets they are offering are for c20, RWD.

Any ideas? Originally, I was also hoping to convert to a 2-way system. But I gave up, since the first challenge is finding the right booster/cylinder.

Thanks and regards from Switzerland
