17" steel outer wheel

Does anyone know where I can purchase a 17" outer wheel that will run tubeless tires.
I'm planning on welding on my current centers on these outers if I can ever find one.

My next option is to go hunting in the wrecking yards..........

Thank you in advance,
Mike

Edit: Miller has 16 and 18, no 17".

Bringing this back, can you find 17" centers? I've searched but came up with tons of ebay links.
