69 904 Trans swap

About 10 years ago I put a 70's 904 in my 67 Dart GT with a 273.I cant remember the name of the place that did it but I had the torque converter shop make a custom converter with the front half of a 67 273..and the back half with the newer 318/360 style spline.So it is possible if you can find the right shop to do it.
