I guess it could be done, but now you're cracking open the alternator. My advice would be to trade it in on a nice fresh rebuilt for about $125.
If you were to replace them, I'd guess at the specs from the requirements. You don't need high-speed diodes. For a 125 amp alternator, I'd want to see 150 or 200 amp forward current, and the PIV (Peak Inverse voltage) can probably be 50 volts or so - more is OK. These would be classed as rectifiers.
I'd just replace the alternator.
