Contact Jack at Royal Steering wheels as he can produce pretty much any finish you want. Picking mine up like the one below but with blue stitching etc from him this Sat on an exchange basis for my OEM wheel.
He always feels offended if members are there and don't contact him as he was a UK member and big character on this forum until he moved over there this year. Send him a PM.
When I purchased my pro bolt strut bar bolts 3 years ago they only did them in titanium which cost me a whopping £100. Unless things have changed they don't do them in stainless steel.
