Check with Discount Tire Online. I purchased Konig Rewinds(16 in) and 205x55X16 Michelins for my 77 280Z for right at 1000 new shipped to my local Discount dealer and installed a year ago. Check them out.
Ben, I would be interested in the 280z version but can not pay before March 1(maybe 24 February, I need to check my funds). PM me or email me at racer47201@aol.com. Thank you.
