Big issues with BB mounts on Dart!

Everything starts from the trans mount. There should be the same offset at the tail of the trans as there is at the front of the crank (for what it's worth I've never had to measure this). Hopefully these pics will help. This is the 440 in my son's '67 Dart.P1011295.JPG P1011296.JPG P1011297.JPG P1011298.JPG P1011299.JPG P1011300.JPG P1011301.JPG P1011302.JPG
