master cylinder for 4WDB

[slickj52003]

converted to four wheel disk brakes and am still using pwr master set up. Is there a drop in replacement Master Cylinder for this? I am already replacing the proportioning valve but it was also recommended to change to a disc/disc master cylinder.Please help or provide a contact who can. Thank You

I'm using

PN M89160
which is a "dorman" number for 1968 corvette 4 wdb.
Rockauto has them for $28.99 w/no core charge.
1 1/8 bore, I use an adj bias valve.
Summit Racing SUM-G3905 - Summit Racing® Brake Proportioning Valves
$38.95
this is on my 57 chevy with 4 wheel disc brakes.
when you hit the brakes, the whole car squats and STOPS!

I bought M/C from 87 Pontiac GTA...it came with 4 wheel disc brakes. Get one at AutoZone or AdvanceAuto at a reasonable price. I have B-car 12" front disk brakes and Baer rear disk with stock 84GN hydraboost.
