If you want to use a Dodge 727 from behind a 6BT then all you have to do is find a 6BT plate from a member here or a yard. As far as I have seen I don't think the 4BT came with a Dodge plate.just recently became interested in swapping a 4bt into my 72 scout . was wondering what year 4bt would be less of a hassel as far as electronics, and if they make adapters for my t18 or 727 tranny? thanks
