John you are out of luck when I bought my new wheels form the USA I threw the old ones out, end caps and all, as they were taking up to much room in my garage. Keep plugging away and you should join here......

NECO has been a huge source of help and information from the day I joined and a ready source of all kinds of parts.
You have got yourself a great car.........every day I walk out of my house look at mine and say to myself....."Self look what you get to drive today yohooo".
You will also have to get used to people coming up to you in the street and asking "what kind of car is THAT???"
