Cool. Never had a problem with Tamiya customer service, just wasn't sure if they would offer up the parts sans payment or not. But I suppose, since it was missing from the kit (even though it was an Ebay buy...shhhhh).
Not to go off topic, but someone else that has great customer service is Pegasus. Had 2 sets of their wheels here in the shop, each one had 3 of one design, with an orphan 4th, e-mailed them with the problem and they put the missing wheels in the mail to me the next day.
