Well, i just scored a dana 60 front and dana 70 rear from a dodge SRW 1 ton. Im gonna regear and use them in my K5 project. I was wondering about disk brakes for the 70 rear to get rid of the 150 lbs of drums. Im 99.9 percent sure that 14 bolt bracket wouldnt work. But i was told you could use the same parts by opening up the centre hole in the rotor and building brackets. Has anybody done this before??
