Sorry for the late reply, just got back home from surgery.
The place I purchase the Type A trans was from A to Z Wholesalers 11100 Harry Hines Boulevard, Dallas, TX 75229.
They have a minimum of $40 purchase w/out a wholesale account. Im not sure if they still have it in stock. I also found a Dollar Store in Irving that carry the same brand (singles), however the last time I checked them they no longer had it in stock.
