Why is there a chevy dizzy in my 360?

Considering there should not be a gear on it at the bottom for mopars I don't see how it could be a chevy distributor. Are you sure they didn't swap out the internals into a chevy housing?

No gear on the end.. And i'm not sure if they did swap the housing, perhaps. the PO did lots of 'questionable' things on this car.
I was looking at this link that made me think its a chevy dizzy. I'll get pics in a bit..
