No real urgency, just thinkin' - there's gotta be a way to swap rear end gears in these cars. Has anyone considered swapping in a Police spec. "HAL" with a set of 3:90's? Essentially swapping in a complete police upgrade package (drivetrain) I'm assuming the `06-`07 3.5 Police came with 5 speeds w column shift?I know I've seen that on another post.
BTW, why the sense of urgency, aero?
