Steve, we were getting those airbags from a major truck spring place, but they were special order, and we would wait months till they accumulated enough for a Firestone production run. About two years ago, the distributor told us they would no longer do that. To the best of my knowledge, Newell is the only stocking source at this time.

But knowing the interweb wizard you are, I think you will probably prove me wrong on this. :-)
