Electrical Panel - Main Breaker over heating

My main break was overheating and kept tripping. I check and tightened all the connections in the panel but it overheated and tripped again. So I call the power company to come out and shut all the power off coming to the house. I pull the pulled the main break and it looked in good shape. No melting or burning of any kind. I then started pulling the breakers off the A phase which was the side that was very hot. I pulled the first block of breakers and found where the problem was. The copper bus bar was burnt where it connected to the main break. It was loose when I touched it and very badly scorched. So my question, Are their replacement part for electrical panels? I have a Seimans mc2040mb1200r panel and just need to replace left side bus bar. or is that even possible?

Not sure if that is still a panel in production or if the guts are replaceable. If so you might be able to change out the guts. If not you are looking at a new panel.

Thought I found a listing on a new panel but did not.
Haven't found any replacement internal parts yet either.

I went to a local electrical supply shop and they are ordering me a MC2040B1200JLC which is very similar. I'm going to see if I can replace the guts. If not I will have have to replace the box.

Thanks for the comments.
