Default JETT .90L Piston Connection Problem

I have a JETT .90L about 10 years old and the piston connection to the crank has wallered out. {Wallered - To make a hole bigger by reaming it to the extreme.} I have sent emails and phone calls to Dubb Jett to see if I can get a replacement part, however, I have not been able to get in contact with him. Do any of you guys have machine experience or suggestions on how to repair this connection? It's been a great engine, tons of power! I sure wish Jett Engines would respond to my email! I sure would hate to have to send it to the scrap heap!

In the pictures you can see as I move the crank the hole to the piston connection does not stay symmetrical and the crank "sinks" up into the piston connection. You can also see where the piston has scarred the bottom of the crank case.

Looking for solutions.

Thanks,
Jerry
