All good….

Works and fit as expected. Only downside is TCI doesn’t offer a high enough tooth range to cover the gear ratio and tire size in our 66 Mustang.

Item shown in sales photo was not the same as I received. The part I received still worked, thank goodness. It was disappointing because I searched for a specific one.Delivery was great and fast. Great customer service.

Got me within 3.5 mph of where I need to be. Did a complete rear change and the gears went to 4.10 in my 97’ Cobra.
