Wow! Thanks a lot 6T9 ! This really helps me out.

I noticed on the Napa site that if you have 11" rear brakes, it shows you a Master Cylinder with Fender side lines. Only if you select the 10" brakes can you get the engine side brake lines..

Does anyone know why this would be a different master cylinder?

And did having 11" rear drums mean that you generally had drums all the way around vs. 10" for a drum/disc setup?

Thanks !
