"Thank you so much for having this collection of bus parts that are no longer in production. You really are a life-saver." Jonathan R."I had all but given up hope that I would be able to find that air bag. But you had it, shipped it out right away, and now my old MCI 102 C3 is back in action. Thanks Vintage Bus Parts."
