4.78, yes sorry.
trying to come up with a plan that maching new dual 19.5 could bolt the my truck now, but then bolt to same gen dually or 03' up dually if needed...
ya i think i remember looking at yours now. mine would need hub centric inner, and lug centric outter.... could just have vic put cones in the lugs on the wheels that wouldn't matter on a dual with the correct lugs (that i dont have anyway on SRW)
