1987 dodge diplomat alum. master cyl, use the orig. splitter block for equal distribution to all 4 wheels, has about 2 times the brake pedal pressure of power brakes on my 68 4 wheel disc fastback. Happy w/ it ! Been a while but if I remember , I gave $38 for the master cyl. at o`riellies. a few yrs back. I did use an offset mount on it, 1/2" thick, 2 to 4 bolt adapter. U can lengthen the master cyl push rod ur self, no big deal. cut it in half, thread both pieces, put it back together w/ a threaded coupling, adjust it to the thickness of ur adapter, weld it it and then dress it up to make it pretty. I turned mine in a little lathe. WAY CHEAPER THAN BUYIN A BUNCH OF STUF AT INFLATED PRICES.
