Are you using a new aftermarket master cylinder or a different (obviously) OEM master cylinder off a newer Mopar car ? If off a Mopar use the valve that would have come with that MC. I never found a need for the adjustable type. (pictures of a Dakota MC and valve in a my '56 are available)

Whoops to early and not enough coffee, you are going to have to do a search for which MC works best for your car, sorry.

people claim the 1 1/8 isn't big enough to move the fluid, there is a nice mopar that is 1 1/4 that people claim is big enough.

search and you will find some good threads

The size of the caliper piston will dictate which MC you need. My disc swap uses the 2.95" caliper and a 1 1/8" MC gave a low pedal, a 1 1/4" MC worked better.

http://therammaninc.com/products/Mopar-Master-Cylinder-Guide-1967-1... I think 1-1/4'' is out of the question. Most people who use mopar masters with disc brakes use a 1-1/32'' master.

The other problem is the rear brakes. The stock rears are best suited for 1 1/8" too. Using a smaller bore master on my Coronet with stock rears makes for a consistently low pedal and is therefore more sensitive to the rear adjustment. So I end up adjusting it more often as it wears. Use a larger bore and the adjustment position isn't as critical.
