1970 442 Alternator P/N 1100890 needed

Hello,
Seeking original alternator for my 1970 442 W30 w/AC built last week of Oct '69. I believe the correct one for my vehicle is P/N 1100890. Any help will be greatly appreciated.

I have seen the 890 with 55amp and 63 amp. Both are for AC. I think the 63amp was for rear defrost,or possibly power windows. Something that took more draw.
