I need some info on a bell housing

Al,
I'll be the first one to profess my lack of expertise, so if someone chimes in to the contrary listen to them not me. But I believe the 9-1/2" clutch is for a plain-jane slant and 3-speed. I have a slant 833 OD that came out of my 82 D150, and it's a 10" clutch for sure. I can get more specifics if you need it. I also have a slant bell and 833 OD that came from an F body that will fit in an A body, I can compare the two for fitment if you need it. Sorry to say, if you tossed that ring it sounds like it's the one to adapt a small hub hole to a large one. I have one of those too and can get measurements/photos if needed.
