" From: farna@xxxxxxx " " I'd check with Advance Adapters and make sure there isn't an early to " late six bell adapter (I wouldn't be surprised if Andrew has done that " already!). haven't done that -recently-... " The bell on the BW trannys is a separate piece so the trans " could be used on many different makes. AMG could easily have made " another bell for the newer engines. I do believe you are correct " though, that the early bolt pattern was used. It would have been " cheaper and easier to change the block casting than to tool up for a " new bell. I've seen at least one mid 70s postal Jeep with a small bell " pattern and M35.
