Bolt-in sprag in Canada?

I heard somewhere they quit making the bolt sprags for the 904's recently. I then read where one of the aftermarket trans people (don't remember who) had bought the rights to start building them again. You might haunt the aftermarket folks (TCI, Coan, Dynamic, et al) to see. Try Torqueflite Patty on eBay, at one time he had some.
