OK, to get this out of the way, the B&M spring is 1.928 in diameter and the one that was in it was 1.828, so a hundred thou bigger than the one that was in it. The one in it was purple? maybe a transgo? I don't know. The instructions say to use the spring but it's too big. Guess I'm gonna call B&M again tomorrow and see what i get for answer the third time and this time I'll have the instructions and the measurements with me.
PS. The Kit says it's for all 727, 904, a-998 and a-999 trans, between 62 and 78
different kit for 78 1/2 to 96
