Swap 904 to 727?

There is absolutely no reason not to keep your eye out for either rear end, or any parts you might need in the future! 8 3/4" are out there, you just have to be patient!! You can find one in the $500 range, it will have a one legged but will still be enough for what you need, and you can always continue your search for a better enter section to swap in!! This hobby is meant to be enjoyed for a lifetime, deals will come to those who are patient, observant, and diligent!! I'm rooting for you, you're among friends here with our 66's!!!
