Need Help Completing My Matchbox Viper NBA Collection

[Kurt]

Hi all- I've been collecting the NBA Matchbox Collection for quite a while. Through hours spent searching toys stores and the internet, my collection is just about complete (except for the ones that weren't produced to sell). So, if anyone here has extras of the Philadelphia 76ers or the Miami Heat for sale, or knows of anyone that does, please let me know. All help is greatly appreciated! Thanks!
