What Master Cylinder? and more

Rumble, Thanks!

#3 ??? That's it just adjust the rod legnth? I thought there was an issue with cable legnth from the backing plate to the E-brake "arm"...

#2 I have a proportioning valve... one inlet one outlet. Therefore, a "T" to the fronts (full pressure) and thru the valve to the rear. Can't see why it wouldnt work. The only reason the front and rear stock lines go to one
proportioning valve is for the 'Idiot" light on the dash (far as I know)

#1 A master cylinder part # anybody?
