Early A body 4 speed bell housing

64-66 cast iron bell housing for Slant six and 4 speed. Different than the aluminum 3 speed. It'll have the unique to /6 starter mount and I believe the bore diameter is 4.35.

Or....if someone has an adaptor ring (or source) to mount a 65 4 speed trans to the larger diameter Overdrive bell housing, I can use that.

Thanks
