It is critically important to match the fluid rates and volumes of the existing master....and keep the length from the firewall to the back of the master the same.
Regardless of your front axle.....where did they get whatever you have for a booster and master now? Are there any name/numbers on either one?
NAPA usually has pictures of the masters in their books....you might find a helpful counter guy who will let you peruse the book and see what you can find....knowing original application would be a big help....
Did the guy who did the brake mods ever come to the Zone? If so let me know his user name if possible, and I will look up in the archives and see if I can find anything by him that would help you...
