Need a simple answer about a Horn

couldnt tell you as I have never had a tough wheel myself.

I know with most aftermarket steering wheels you need an adapter kit whitch consists of (normally) an aluminum spacer that on one side has a larger hole that slips over the steering shaft that you run your lock nut down on,sometimes there are like 3 small screws also on that same end that help hold it and then on the other side there is 3 larger bolt holes for the steering wheel itself to mount to.

and since the spacer mover the wheel out and creates a gap in most cases, a beauty coupler is supplied also.....this is what hides the gap between the column and the wheel.

there are plenty of folks here who have swapped tough wheels before so I am sure someone will chime in and give you a more exact answer, good luck
