67-68 GTO Disc Proportioning Valve ID ?
 

I'm trying to find out if the proprtioning valve I have is correct for the 4 piston set up.

I can't get the picture to post, but the number stamped in it is 7-037.

Ring any bells?

37 day of 67 or 77 or 87 etc

This will be more helpful than not. I have 3 such setups here (in my shed) that I could check later.
