I would check with Charlies Fly box (Arvada, CO). http://www.charliesflyboxinc.com/
He can usually order it from Whiting Farms if he doesn't already have it in stock. I have ordered a few items from him in the past and they mailed it directly to my house. It's been a couple of years but, great service and never had any problems.
Another person that can probably do the same is Theo at Colorado Skies Outfitters. He post here alot and always has great info. http://coloradoskiesoutfitters.com/
It would be nice to throw some business his way.
Hope this helps,
