Looking for info on drop spindles for a 64 c-10. I have found complete 2 1/2 drop kits for approx $1000.00, I guess the only way to do this is to convert over to disc? Are these kits as straight forward as they appear, has anyone experienced problems with this swap, or does anyone know of a more economical way to do this. I have considered buying drop spindles and gathering everthing else at the boneyard, but am not sure what year parts I need.
