67 411 alternator substitute part?

[mdwolfie86]

Hello, I am a new member and I’m happy to be here. I am also here because my dad has a 1967 Datsun 411 that is his daily driver and recently began having issues with holding charge. We removed the alternator, tested it and found that the diodes are bad. We then began looking into getting a new one and it appears they no longer make this alternator…? It’s the original Mitsubishi. Does anybody know if there is a substitute alternator that may be used on these or any info at all would be greatly appreciated.
