I am having a hell of a time finding a brake master cylinder for my 1972 RX 2. Can't even find a rebuild kit. Does anyone know, or has anyone used a 1979 RX 7 one? like this.

Also if this wont work, has anyone had success with anyother brake master from a different year?

 

I have been wondering this too, I am going to see if I can get my fc one to fit, other wise I just might make something. I let you know.

 

I know where to get it rebuilt. In fact, the master cylinder in your "FORMER RX-3" in in the works.

 

I don't think this one will work without major modifications. I think the threads are different, and the hook up for the brake lines are on the other side.

 

Pm'd You.

 

Yo Jesus!
Get a '79...take out the top stud and drill the hole out a bit as the Rx2 has a stud on top going thru the firewall from the inside. Put the lower stud thru the firewall hole and use a bolt in the engine bay on the top. The line thread is the same too! Really easy.

 

So a 79 will work with a little effort.
