Eberly Trailer Spring

Hi I'm looking to see if anyone knows anything about the spring driven arms that hold up some Eberly trailers. For people who haven't seen them before they serve a similar purpose to gas springs in Cobras but using a spring and lever. The trailer for me and my partners Libelle has them installed but only one side has a sufficiently large enough spring. This means that one side of the clamshell has to be secured manually while the other side stays up on it own. It also means that the half clamshell opens and closes somewhat sideways due to an uneven loading. I'm hoping someone has either a part number for the arms, arm assembly, or just the springs encapsulated in the arms so I can buy a new spring for the week side. I have done some pretty thorough googling and come across very little usable info. Also for those still a bit confused as to what I am talking about here is a few pictures of the spring loaded arms on our trailer. https://drive.google.com/drive/folde...l1?usp=sharing
