Distributor Clamp Upgrade

Thank you cavemanmoron for a reply.
I have previously search Slantsix.org & am following a related thread with no success.
I have also searched the Slant six sub forum.

I decided to try this area because early A body V8 people might be here willing to check dimensions on a spare clamp they might have ....which might have more success than discussing getting V8 dimensions at a slant forum.

If I get dimensions I'll add it to the Slantsix.org distributor clamp thread.
