I know I have at least one 605, maybe more in the "to be restored when I retire" pile
I have many other parts motors if you are looking for something to fix yours. I still have a couple "Y" fittings I reproed. I was the first person to repro the headlight soleniod plastic part. You can PM me if you want to talk further. That ebay auction is just pie in the sky price, no wheres near reality!
