There are literally hundreds of steering hub adapters on eBay. Many of them are adaptable to the simple hub adapter made by grant steering wheel. The correct grant kit for our capri steering column splines is out of production but it’s part number is 3295 and they do show up on eBay.
Important for your conversion is the stacked height of the adapter/adapters you wind up using compared to your current adapter height.
