Konig wheels needed

Hi

I would like to have a set of konig wheels on my 240z, may be in 14" or 15". Anybody knows someone that sells them at good price?

I read in some "old" posts before that, there was a company that sold them 55 USD per wheel!

Does anyone knows if that still available?

Another question that I have is what`s the size of the original tires on the 240z!

It is 175/70/R14 or 175/80/R14?

Thank You
