Good morning, "Guppy1"
You don't give us much to go on. You might want to add a little something in your "signature" to tell us what type of RV you have, maybe year, make and model. Drilling into your profile info it looks like you may be in Iowa, but that's about all I could find to help me help you. We had an Onan QD generator in our '06 Dynasty, but I doubt if there's much useful information in the owners or parts manuals that I have. But take a look at this link and see if it gives you any hints.

Also, try PPL in Houston, TX. They are amazing at coming up with hard to find "stuff".

Googling "Onan 327-1461" did produce several hits that look like they might be useful.
Good luck in your search and have a Happy New Year of RV'ing!
