If you mean the kind pictured, standard with the 986 Boxster, I have my original spare from my 1998 car. Used one time for 20 miles. Email me -- trygve (at) bombaydigital.com to discuss. Looks like ebay prices are $200 and up.
thanks folks, but that's why I'm fishing..... don't want to spend $200. I'll be working with Trygve as soon as I determine whether this will fit into a '73.
