You've got a 904 in there don't you? Do you know what year the tranny is? I want to put the 904 back behind the 360 in my Valiant this time, but it's a 66 and I believe there's some small differences between the 66 and the later ones which makes it difficult to find converters for them. Good luck with yours, and don't you just love waiting for one part when you have another new one ready to go. :)
