It was and adaptor. The splines were right but the taper below the splines on the shaft is different. It ended up hitting the taper and another part of shaft(hard to explain) but it is very solid when the wheel is bolted on. Not many miles on it but i don't have any worries about it breaking.
Got it on eBay. It's for Honda cars. Part number HUB-OH-124-BOSS. Did some trimming so it went farther on the splines on the wolverine column. Then bolt any 6 bolt hole steering wheel on it pretty much..
I had that same exact steering wheel, was a bit more faded though. If you want a 14" wheel, you can use a stock Arctic Cat take off, it has that same 6 bolt pattern. I found mine used on Ebay for $10. Not sure of a source for the adapter though.
This adaptor is aluminum and has six hole pattern. I bought from ebay for a 2011-2013 Yamaha Rhino, $50.00. It did rub my plastic slightly so I chucked it up in a lathe and took a 1/4" off the bottom that's why the bottom is shiney , I removed the powder coat.
