The problem is the bike has an upper frame but no frame underneath. I have been told I need a subframe. I think it would be easier to find a needle in a haystack. I have been all over the internet. The service manager at my cycle shop has talked to several other shops without any luck either. I am ready to send the sidecar back. If anyone has some knowledge as to how this can be accomplished, please let me know.Thank you, Dennis Keenan. Maywood, NJ MOA #148168
