Anyone know if a P series alternator like the one in the ebay listing below could be used on a 97 Chevy C2500 / 5.7 Vortec gas engine, Eighth digit on vin is R?

No problem, I was hoping you saw something that i may have missed. The P series alternator looks exactly like the other ones. First link below is the alternator that fits the C2500 and the second one is the P alternator, They look identical to me except for the price?

They are physically identical and mount the same however i was told the voltage regulators inside are different.
What's the electrical system in a step van?
If it's 12 volts the regulators should be the same; however, it could be a 24 volt system.
I've never opened the hood on a step van.
