I use 85 diplomat when I buy them, 15 bucks, and you will need a junkyard resevoir, they dont come with them. Hmm, big bore hard pedal, no thanks. The diplomat one feels the best. I make a 1/4 inch alum plate that these bolt too, real easy, the big hole in the center is off set a bit. I traced a four bolt master pattern, then centered the two holes in between the four holes, I tap the two holes and put short studs in there, and done. The lines are backwards on the newer ones, The rear port is the front line on the alum ones.

What brakes are you running, disc/drum or disc/disc The most you would need is a 1 1/8(never heard of a 1 5/8 on a car... must have been a typo). Did you start with manual brakes or power. The pedal ratio is different between the 2

Use the F-body aluminum master. The truck master has too large of a bore when used with stock, passenger car brakes.
The adapter thickness makes up for the difference in master cylinder design. You do not need to modify the original push rod.
Dr Diff, is the F-body a 15/16" bore(which I believe should be fine) also hows the difference made up with using the adapter plate, is the piston moved rearward? thanks
