Im getting ready to do a major performance upgrade to my truck. The only thing is i didnt account for new gears, just wondering if anybody had some good 3.90's or 4.10's laying around they could part with. Im excited about this project im getting ready to do TOG headers, VR King Cobra Ram Air, PCM, E fans, And a shift kit. This should compliment my Corsa exhaust nicely i believe. Any help is appreciated, thanks guys
