Hi
It is my understanding the accumulator color defines:
Blue 450 lbs. of NO2 for disc/disc
Gold 350 lbs. of NO2 for disc/drum
Silver unkown of lbs. from heavy duty spring inside probably used more on drum/drum.(pirate 4x4com)

So i have a gold but running all wheel disks. I assume I would need a blue.
Anyone have a part number for the hydroboosts and mc? Im running calipers out of a mid nineties chevy 3500 or p30.
To buy a new one I need the vin# which i don't have and there are multiple choices.
Also are the master cylinders the same as a disk/disk or disk/drum
Thanks
Chris
