Neither of them have external weights other than the thin strips in the photos. The high stall that was with the 340 (73 externally balanced) go figure. One of them I have no knowledge of. The gray one came out of the an old drivetrain I had in the car that drove fine, but I didn't drive it much because the car didn't have a windshield at the time, so I don't remember much about the stall.

Transman l take closer look for those numbers.
