MDX Oil Pan - threads stripped

Hello all, I made the mistake of not replacing the gasket/crush washer on the drain bolt and have now stripped the threads in the oil pan itself. Temporarily have fixed using an oversized bolt from Auto Zone. Dealer quoted $535 + tax for oil pan replacement. Looked up pan part online (11200-RYE-A00) and it's around $100. Is there a DIY for oil pan replacement? Any recommendations?

Thanks!
