1981 Kawasaki 440 Standard (KZ440-B1) LH Side Battery Cover 36001-

Hello! I bought a 1981 Kawasaki 440 (KZ440-B1), and it works beautifully, runs great and it's just an overall blast to own. However, some of its parts are over 45 years old, and I wound up losing the left side cover, battery side shell! I've been searching for days for the shell on Ebay, various Kawasaki vintage part sites and it's apparently a very common issue with these older bikes! I am willing to negotiate the price if the shell is available, and I will provide an image below of the right side cover I have, and circled the left side cover shell I lost. Thank you for your time and understanding!

the kz400b/c side covers appear to be the same. some have an emblem recess. their frames are similar to the 440b. some riders secure the side covers with hitch pins after drilling holes thru the tabs. especially w individual pod filters.
