Lude Generation

Evening folks
quick tale...I've bought a mugen 3 steering wheel and HKB boss from tegiwa for my gen 4 BB4 lude,but fitted the boss and its a midges to big on the spline.Ive since contacted tegiwa and there scratching there heads and can't seem to find a part number that suits so I'm wondering if you experts on here could help me out.
thanks neil.

On ebay it seems to be mostly Momo adapters that are listed so maybe worth checking them out rather than HKS

Thanks for the reply, they have contacted momo and are waiting back for an answer but I've given them spline diameter and number of splines so ill send this one back and have a look on eBay.
i just thought one of you guys might have a make or part number so i could go off that, but ill keep looking

Yep, I'm with vanzep - Momo adapters are the common ones you'll see around for ludes.
