I have a 1997 FC501 that I am restoring. I was just able to get it CA street legal(don't ask). But that lit a fire and I need some parts. Curious what the compatability is between other years and models. Found a 1991 FE501 on craigslist that looks the same but I just don't know enough about Bergs. I doubt the 1991 will work but a year range would help... Thanks
