You need to replace the alternator. The other parts are just as old as the diodes and will fail shortly. If you don't replace it you could overcharge the battery and any other electrical item in the car could be damaged by high voltage.

AS stated replace the assembly with a quality one -not discount one - and also recommend replace alt/serpentine belt at same time(draw belt routing diagram BEFORE dis-assembly ) use good belt also. chek tensioner while belt is off.Have radio code handy for resetting after battery dis-connect.Make sure battery is FULLY charged before starting with new alt. May also end up havingto reset driver window 'auto-function'. With door closed and window up, hold switch 'down ,continue holding down for two seconds after window is down. If yours also has 'auto-up feature' Then same on the way back up hold switch and continue to hold for two sec.after it's up. Then check for proper operation. Good luck.
