Any idea where I can find a spindle for my 1970 plymouth duster

Hi everyone,

I have a largely original 1970 plymouth duster. 318 car that had 10" drums all the way around. I did a SBC front disc conversion and have been happy as can be. Sadly, it appears a race worked loose in one of the rotors and ate up the bearing. Rotor is now seized on car. I'm concerned the spindle may have been compromised. The SBC kit is able to accommodate the factory spindle - any suggestions on where I may be able to find a replacement spindle?

Thank you.
