  That is som very good modeling on the buggy bodies. The tires on the
 other hand. Ok I know that you know, I just wanted you to know, that
 I know you knew.

  I have a presnt for you. Those tires were bothering me so much that
 I hacked out a couple of possible solutions for you. The small image
 pretty much tells it all and the script is short so enjoy.
 Please have them installed before you post again.
