According to Bosch the pulley dia is 52mm. https://www.boschautoparts.com/p/100...ators-al0807n- Pulley of the OEM D2 alternator (2004) measures 52mm too. So perfect fit and nice find @Sdrows !

 

Hello JohnZo. I seen this message a while ago. grabbed the flashlight went out in the rain and checked them out and yes they are the same.
Always complications ain't there.

 

Thanks Discorama. Many of the posts on these forums are 10 years old or better. Most part links and numbers go nowhere.
This one might be good for a while

 

For those who wouldn't mind a few more options sourcing a 150a unit, and maybe save some mullah, search the Range Rover 4.6L (94-02) on the Rock Auto site. The AC Delco gold brand 150 amp units are around $150 these days. I got my Bosch unit a few years ago there for $127 shipped.

 

Hopefully the last disco repair of the year completed
Shoe horned in a group 65 diehard Platinum AGM battery.
I'm reasonably sure that Odyssey 1500 extreme killed my alternator and the alternator helped kill my battery although maybe 18 hours in a charger will bring it back to a full life. Tired of fooling with it though maybe this simpler diehard will be idiot proof. No deep cycle business to fool with.
Thanks again for all comments and suggestions.

 

Positively a better price I paid roughly double but it did came very quick
