Ok, thanks for the replies, and thank you for clarifying about the transmission cover. You have reminded me that I also need the magneto cover, though so if anyone has one of those let me know.
Also, how do I know whether I have a 504 or a 505? I haven't been able to find any numbers on the engine itself or on the ID tag on the moped.
Maxmagnem, thank you for the offer! Let me try and find a source for a drainplug and then I would love to pay for shipping for your cover.
Hoppeness- I looked at your ebay auction, mine is a '78, will your sidecovers be compatible? They seem to look the same as earlier ones. Does your Eagle have a 505 engine? Just want to make sure that the exhaust will also be compatible. Is it a right hand side exhaust? It seems Eagles have right hand exhausts and Balboa's have left hand exhausts, I think this may present a problem.
Thank you for the encouragement, Pat
