Kris's car had no viscous coupling and a bit of metal safety wired in to hold the output shaft in place. Of course that didn't work very well as evidenced by the shaft popping out and leaking. We got a viscous coupling and a ball bearing today, but we need a snap ring and nobody had one. We'll be out tomorrow if and only if we can find a snap ring and get the tranny together with enough time for the RTV to dry. Not very likely given the apparent lack of snap rings in this town.
