On my 86, I wanted to retain the low-pressure sensor built into the stock prop valve (later cars have a low fluid sensor on M/C). So I gutted the prop valve per the SSBC instructions (they only had you remove the spring and plunger, but retain the tube and stock plug with the rubber center). Worked pretty well with the SSBC rear discs (same as the T/C/93 Cobra). The problem wasn't the gutted or manual prop valve; it was those completely mismatched 73mm SVO calipers. Anyway, ran it that way for 15 or so years until I swithced to the sn95 Cobra fronts (retained the SSBC rears) - better match. At that point, I replaced the stock prop valve plug with the FRPP piece - by the way, both MM (brass) and LMR (aluminum) are reproducing those plugs.
