    I'm looking to replace my 8" rear end with a 99-04 mustang rear end. My current rear end is 61.25" and from what I've read the 99-04 mustang rear is 62.5". I want to be able to run modern wheels in the future and with the extra width I should be able to run them without spacers. I know that the gt rear end came with 3.27 gears but wanted to run taller gears until I get everything for turbo. Would a 3.55 gear be to tall for a gt40p motor, 70 mm .68 ar turbo, with AOD transmission?
