Dual reservoir master cyl. for '63 Dynamic
 

Hi. I'm looking for a dual reservoir replacement for my single reservoir master cylinder on a '63 Dynamic 88. Any idea where I could find one, or a conversion chart that will tell me what I need?

I should let you know, I had a '63 Super 88 parts car, and it had a whole different stock master cylinder and vacuum booster than my stock Dynamic 88. (Supers and Dynamics are pretty much the same car except that the Super had a slightly more powerful engine and more options...don't know why the master cylinders should be different.)

It still has the stock drum brakes. Thanks for any help you can give.
