Ford Mustang كوبيهGT 2008 Manual Gasoline mileage: 300 KM or more 3.55 differential fits directly on any Ford car with an 8.8 differential. I bought it and it came with a clean center, and the ring and pinion are all clean, but I haven't installed it yet and it's still in the shipping box, unopened. Whoever wants to inspect it is welcome. Note: When installing the differential, it must be properly balanced by someone knowledgeable to avoid whining. It was offered for 600 SAR. No warranty.
