I want to upgrade my rear end to 3.73. I'm new at this forum and this is my first Mustang. I need help on part #s and where to buy cheap. They came with 8.8" Rear Gears from the factory, right? I found a Ford Racing kit at eBay listed for $248.33 w/ free shipping, ford racing part #M-4209-88331 and #M-4210-B2. Is this the one for my car?
