Easy (?) OD Auto Install

My 79 Diplomat and my Dad's 79 St Regis both had that 904 lock up. Lots of them were swapped out back then because of torque converter shudder when locking up.

No one knew what the problem was at first since Chrysler was the first to use the lockup of the big 3.

I had a 74 Dart that had one. Not sure if they came factory that year or if I swapped it in. I remember it would shudder pretty hard if I was in third and just let off the gas. If I accelerated again, the shudder would ease up/go away entirely.
