Andy --
Go here:

and choose COX engines from the menu on the LHS. There will be pictures available --- you will likely want to look thru the Medallions and Tee Dees.
Small world --- I'm from down the road a bit in Murray. Usually, I sign my posts as andrew, but am known to most folks around here as andy.
