Congrats on the RFM! If it were me I'd try to find a replacement or send it out to a professional since the damage is pretty extensive. I would also try posting on RGP as well to get more exposure. I did a quick search and it looks like there's a guy in PA that had a NOS pf a few weeks back that may be worth inquiring about:
