Here is something i failed to answer got this from another member here! Jim still following your rear end build and just curious you originally said that it could be any gear ratio you wanted but now your talking 3.46 specifically. Just wondering if it got too difficult and you gave up on doing multiple ratios and are only doing 3.46 now? Thanks in advance

the multiple ratios was with the Ford 9" diff,, and i already put in and lost 4800 and now they want to modifly our sub frame ,,so it would no longer be a bolt in so i said drop it,, they are working on giving me back 2800 because everything they did could fit in the new mustang if they sell it i get money back.
