The first 289's had splined adapters the splines ultimately were deemed insufficient when HP and torque were increased and the studs were adapted from other racing fitaments. You couldn't clamp the wheels tight enough otherwise. Any takers?

I know of two recent cases where the drive pins on a Cobra were sheared off because the knock off was either not torqued properly or there was lubricant on the mating surfaces. You need the pins and the clamp load to retain the wheel.
