WTB: 4 disc prop valve, '91 RS

I'm looking for a 4 wheel disc prop valve to fit a 91 RS. I switched from drum to disc and the factory valve isn't cutting it. I would prefer to find a good used one before spending the money for a new one.

Should you be unaware, there are two designs:

1st design: M1.0 tube nut threads (For 1982 - early 1989 applications)
2nd design: M1.5 tube nut threads (Late 1989 through 92)

Also, there's the following, a cheaper alternative than new:

Hmm I was not aware of the modification kit. I was aware there were 3 diff designs, I did have the years wrong though. Know of anyone who has tried the kit and how hard is it to install?

As I understand it, there are only two designs. I edited above for the sake of clarity.

You might contact Ed. My guess is that he does the modification in house and sends the valve out, but you might ask on the brake board.
