Help, my seat is broke

I am in a federal disaster area, and now the metal part of my drivers side seat frame has broken (the part under the upholstry that the power seat track bolts to). Does anyone know where I can buy one online, all of the local junk yards are still closed (along with most other businesses, the Post Office just started limited delivery today) I have tried JB Weld, but it will not hold.

Thanks Ike
