I have an Akron 107 and a 103. Both generators are plugged and I have found no source of new or OEM ones. I am going to try the soak and heat procedure but in the meantime I have gotten a 1/16 IPT tap and die and I am going to use a 55 generator, remove the flare and fitting, then using the die cut a short thread on the end of it and install it in the lantern. I think that should work for now. Not original but practical.
