You'll just have to figure it out as you go. Mopar master cylinders use oversize fitting on them to keep people from installing them wrong. Aftermarket stuff like Wilwood don't do that. If you buy an aluminum master cylinder from Doctor Diff then it will have the correct fittings. The Doctor Diff master will also have the correct brake rod retention o-ring. The Wilwood master most likely won't have a brake rod rentention device.
Ok thank you, i pretty much thought I would have to figure it out as i go. And i do plan on going with a Wilwood master though. There are just so many options: 1 or 2 piece front to rear kits, 4 or 5 piece front kits, and each of those have different options. Since there are so many options i figured itd be easier to ask here instead of trying to figure it out myself.
