Wow, you have the direct gasser to clark bell, thats kinda rare. It may be easier to go the sae to clark route. Someone once suggested the bell style you have would bolt right up but ive never seen enough parts together to confirm.

Looks like it will bolt to the sae housing.

The SAE bell comes in 2 size's for the IDI... SAE 3 and SAE 2.... The 2 is larger diameter than the 3... Also the 3 is aluminum the 2 is cast Iron.
the stock passenger side exhaust manifold Won't work with the SAE housing it hits the bell adaptor at the side trans mount. check out my Flickr page I have some pics of the SAE 2 bell with SAE 3 adaptor ring I used on my Motor Home engine swap. https://www.flickr.com/photos/racer30/
