Alternator recommendations?

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.
Go with Will's used one. No question. After market alternators for these cars are usually a problem.
Save your old one and have it rebuilt and then keep the one from Will for a spare. I had mine rebuilt about 15 years ago and it's still going. I've never had good luck with chain store alternators no matter what vehicle.
... 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.

Slap in a P38 95-98 GEMS alternator and call it a day. I have had very good results with alternators/starters made by Parts Player. I installed a P38 GEMS Parts Player alternator into my 98 D1 LSE and it went 3 years of flawless service up to me selling it, and I haven't heard a complaint from the new owner. When I bought my 98 D1 LSE the previous owner had slapped in a unit from Auto Zone and it lasted maybe 2 months before it died on me.
He's set with one. 3 year warranty. Now standard on all alternators/starters/fuel pumps purchased.
Old thread.. I know. But just to keep info updated, the maniac motors folks have been pretty friendly and very knowledgable. I think they're in Tuscon or somewhere else in AZ. Give them a call or really, a txt seems to be the way they like to reply: https://www.maniacelectricmotors.co...5-discovery-land-rover-amr3107e-yle10124.html
*I am NOT affliated... Just had a good interaction with them.

I bought one of these for my alternator - pretty easy install...
After three separate diode burnouts on cheap chinese alternators, I finally got a good used one from @KorytheLorry when I picked up his old 4.0gems & R380 (and fiddlybits)... and i dropped it in there and it works great! If I recall, he said this one was his third attempt as well.
I have added a second ~modern alternator where my power steering pump used to be (thus restoring the stock belt size, YAY!) and I run them both. My idle voltage is rock stable now at 13.9-14.1 all the time. It's minimal float charge, with a new (NON-AGM) battery never drops below 13.4-13.5v. I call this a win
* I have since cleaned up the hydraulic reservoir [hose] mount clamps (and yes, the coil is connected too ;-P).
I am adding a second aluminum pillar (at the back ~toward the head) to strengthen the mount; it is fine but the alternator vibrates and torques a tiny big when stabbing the throttle.. it doesn't meaningfully move but I prefer it to be more solid.
The steering reservoir is now mounted directly over the electric pump (near where it is in this photo, but a little outboard (still inboard of the airbox inlet).
