I have a set, dont think I am selling though..
ALso they can be kind of a paint to fit on a cobra..
If your brakes are pretty run down a 1inch spacer will clear..
If not, The easiest thing to do, is get a 4.5 to 4.75 wheel adapter/spacer that is 1.25 inches thick...
Bolt that onto the car, then bolt the draglight to that, using the 4.75 bolt pattern..
If you dont use the 4.75 adapter, you have to trim your stock wheel studs to fit the wheel on.
