@Blackrice , many retailers carry the Flat-4 banjo steering wheel. The ISP add is just one representative company who pkgs the kit together... Which shows you the various parts you would need., including reference manufacturer part numbers Others do as well.. cip1, Sierra Madre, kustomwarehouse1, etc... Do a google search and you may find a local shop near you, save you on the shipping. I'm on business travel in Prague, and a quick Google search identified two shops within a cab ride of my hotel that had the part in stock... You may get lucky and find something near you.
its a common part. Also remember, out of stock now does not mean out of stock in 2-4-6 weeks... Most of these shops do re-stock popular parts.
