Appreciate all the help in this thread. The elder had the Regina off in about 2 minutes today. I purchased a new 7 speed Sunlite 14-28t all chrome freewheel from them for the trouble. Spun right on after I cleaned up the hubs. Put it in the dropout and doesn't appear to be clearance issues but we'll see when the new chain gets here if there's any rubbing. Plenty room for a spacer looks like if it comes to it.
