i am new to pony's, and to street mod's, i have a 2002 gt w/ cai. i wont to do the geers now. i have read lots of post and looked on the www for all my answers, but i still think i need more info. i wont to go with 3:73 because i welll go supercharger some day but that well take a long time because of cash flow. my questions are as follows. 1 do i need anything other then the gears,the bearing kit,the speed gal.,and few bottles of oil? 2 well i need to change any thing out or replace enything as well? 3 well i end up at the repair shop and have the mechanic tell me " you'll need this done as well sir"? 4 dose anyone know of a shop that can handle mod's for my pony in the waco tx area? 5 is there an install kit i need for all the gasket's and replacement stuff? 6 and is it 7.5 in or 8.8 in i need?
