Am I SOL? Where to buy one of these?

This is currently my Daily Driver!

Front Wheel cylinder started leaking on my 70 C-10. Figured I'd pull it and run down to the local parts store for a replacement. The Anchor bolt was seized on (tried penetrating oil/heat, etc etc.)

Then I had the bright idea to have the wife hold the socket while I tried to stand on the handle to break it loose ( after all leverage is your friend). Well the socket slipped off and snapped the nub that holds all the springs for the drum brakes. I have spent hours searching online and can't find one anywhere (LMC/oldtrucks/ebay etc etc). Is Wheel Cylinder Anchor Bolt the right name?

Does anyone know where to buy one, or have one laying around after doing the 5 lug disc brake conversion? I'm located in Shreveport Louisiana.

I am not interested in conversions, just need to get this mean green machine back on the road.

Details:

6 lug Standard Brakes 1 1/8 diameter cylinder/ and anchor bolt (60-72 C10 front drum brakes?)

Thanks for the support
