I got mine from Summit Racing - but most of the larger "performance" parts houses carry them. Get it from whoever is cheaper.
2 more suggestions: 1) Make sure you get the installation kit, also. The steering wheel itself just comes with the brushed aluminum horn button with the Pontiac logo. The install kit comes with the adapter cap for the end of the column and all the parts, wires, and contacts to make the horn work.
2) Steering wheels get a lot of wear from your hands, so I put 3 coats of satin Polyurethane spray varnish on the wood rim.
