63MM busbar source?

I am building a 48v pack with 105ah EVE cells. The screws are M4. The ones that came with the cells are 38MM and they work fine when putting them in parallel but i need to connect them in series with two rows side to side. It looks like I need 64MM center hole to center hole bars. I have looked all over the place and cannot seem to find that length.

Does anyone have a good source for busbar manufacturers that might have this size?

Thanks in advance.

Not sure if this is what you're looking for, but you can order custom laser cut metals from oshcut.com or sendcutsend.com if you want to design your own busbars.
