Body:
Hey Mike thanks for all the great advice. I will check everything I
could over the weekend and once the shop opens back up after
Christmas I will look into the rest.

Maybe we can get together in the spring and and take some pictures
of the cars or hit Englishtown. Better yet maybe we can get a little
get together with other group members as well for a little ASC
MClaren picnic. Any takers?

Ciao, Nick :)
