More then one way to skin a cat. I just did this to my 85 pickup. 1988 Land cruiser dual diaphragm booster got from rock auto A-1 CARDONE 532570. master cylinder from 1994 4runner 4x4 CARDONE SELECT 132711 it has 1"bore. I do need to get a connector for the low fluid light now. Had to bend the lines a little bit but not to bad, worked out pretty well.
