I have a 46' Binder K3. I have a 327/700R4 combo I'm putting in it. I am putting in a 48-52 Ford F1 dropped axle up front with a disc brake conversion. I will have the option to go with Ford or Chevy rotors and will decide when I know what rear I'm running so that I can match the lug pattern. I just measured the 1 ton rear in my K3. (wheel mounting surface) WMS to WMS is 65" Flange to flange is 52.5" Posi would be nice. Not sure if I need it or not. I'm not too hip on the differences of rears so school me here. Will want disc. I know most can be converted but it would be nice to just get it all at once. I've been told that 3:73 gear ratio would be perfect for the 327/700R4 combo. I want to get something that I can find pretty cheap. Either at a dismantler or craigslist. Any advice?
