I am looking for a cost analysis/or opinions between buying parts/levers/seals/ special column tools/service manual to rebuild a '72 C-10 factory tilt steer, column shift vs. buy new w/ALL NEW made in USA Ididit or Flaming River. Also,which manual would include step by steps....shop service or chassis service?? DO new ones use factory shaft & style connecting(w/rag joint) to gear box or require new shaft halves and a u-joint? Spline to double D adapter? Time is not a factor and I have the skills. OR.. IS A vendor available that rebuilds factory units????
