I've got a 1994 with the oem Solaris Silver 7 spoke wheels. Roughly measuring, it appears the center caps are 73mm in diameter on the outer face. Wondering if there are any standard Honda "H" center caps that will fit in there? If so, what model? It seems there are plenty that are 68mm on ebay. Need these to complete my Acura to Honda conversion but don't want to spend $214+ for the ones at SOS. Thanks.
