The height is fine, just a bit taller than the stock factory pistol grip my car came with. The throw is too long in my car with either shifter handle. There is also a shifter kit available for my car to shorten the throw, that has a different handle, much shorter with a ball handle. It has a new linkage as part of the kit also, not just a new shorter handle assembly.
I haven't driven a newer manual Challenger so I can't say if they have shortened the throw in subsequent models.
