Source for Marchal diodes?

New to me 73.5 911T, discovered no output from the alternator.
Discovered both isolator diodes and three of the winding diodes have no continuity either direction. I don't mind replacing the alternator but the chronic D.I.Y. in me wants to repair the part. I suspect a cheepie previous repair.

Anyone have a source for replacement diodes?

Marchal 712 237 02

Thanks~!

Any good alternator shop, NAPA stores, or Ebay. All have worked for me.
