The ones from rockauto work well enough, though I've never had a rover alternator charge higher than 13.9v while D2 alternators seem to hit 14.2-14.4 consistently. Its an odd footprint so there isn't anything else that bolts up without custom brackets.
... or, you can buy yourself bearings and regulator, and rebuild it yourself in forty minutes' time.
Disclaimer: it took me a long time to find a regulator for serpentine-belt alternators, and IIRC I bought mine from BPUtah.com . It is more expensive than a used alternator, but, at least, you have a little longer life expectancy.
One nice way to go about it is to buy a used alternator, and rebuild both - so you'll have one good unit in the truck and one on the shelf.
