Wanted fj40 curved firewall rib to fit brake booster - looking for another one

[LCMoneyPit]

I’m on the hunt for another curved firewall rib. I’m swapping my 67 FJ45 to 70 axles and changing the engine, so this is the perfect time to do power brakes. Please let me know if you have one or have a parts truck you are willing to cut that part of the firewall out of. Thanks
