The Cold Duck,Dana 20,and ZF are in the Bronco working beautifully. 330 to 1 crawl and 19 mpg on 38" BFG KM2's. 400 or so miles on it now shifts real nice and quiet .very happy with this set up now. Adapter and hydraulic hose from Jayson at BC Broncos.Very nice dealings. Master cylinder from 1960 F100 works well nice pedal feel.
