Alright so what are some pros and cons of a propeller style mount like AA sells for v8 conversions? I've done some searching and haven't come up with much more than, some are prone to leaking and they can reduce the amount of twist? put on the transfercase. I'm not entirely positive I understand that last part but on my truck I'm running and old downy adapter that has some provisions for bell housing mounts but I would have to fab those myself so I'm trying to figure out which would be the better design.
