I'm wondering , there is 5 inlets that you plumb into your brake system on the disk/disk(PV4) combination proportioning valve that I'm trying to install and they look like they are all different then the brake line that I have in there now which has a disk/drum proportioning valve (PV2). , is there a disk/disk proportioning valve that will fit the existing brake lines that are in the 87 camaro now?

What exactly are you trying to do? It's not clear. It sounds like you're swapping over to a disc/disc from a disc/drum system and swapping the disc/disc combination (proportioning) valve is the problem?

Which port(s) don't match?

Sorry its a 87 Camaro with disk/drum that I;m swapping for disk/disk. My problem is that the universal GM disk disk proportioning valve doesn't have the same size compression fittings, which makes it a big hassle . so I'm going to try to use the disk/drum proportioning valve that is in it now but install a stiffer pressure spring. Just need the spring number.
