somethings wrong with your OD...I have never heard of gears messing up your OD??? I have 4:10 and wouldn't go with anything less. Get the gears!
and UDTBadkarma get your tranny looked at!
ummmm u sure? because i dont think that's likely. I didn't have posi in mine, and i dont think ford uses posi anymore. Everything is limited slip now... Maybe i'm wrong? But my old 98GT car wasn't posi...
**Tuned*** If you get 4:10 let me know because I am selling my Diablo Delta Flip chip. This would be the correct program for your car (We both have 98 Autos) I need $200.00 for it I paid $400 for from Steeda less than a year ago. I also have a jet chip for the 98 Auto I will sell for $100.00 just let me know. As for exhaust I would go with Magnaflow. All stainless so you won't have to worry about corrosion down the line... I would get Magnapack cat-back around $320.00 order it from partshopper and get a quote from Charris. and then for a mid pipe I would go with Dr. Gas I think magnaflow is a little over priced on there x-pipes.
