I replaced the 16ACR on my Spitfire with an uprated  60 amp alternator from Canley Classics.  The replacement looked the same as the original and fitted without any adjustments or modifications.  This was some years ago and it has performed without any issues.  I realise mine in a 4 cylinder and not a 6 but if your original is a 15ACR, I can see no reason why the uprated alternator would fit a 2000 but you may wish to wait until someone confirms that they are interchangeable.  Canley Classics price is £54.

the only thing to look out for is the handing of the mounting lugs  

most lucas type can be moved to change upper /lower adjusting lugs    but left hand and right hand hanging need to be right 

if the rear lug has a short metal bush fitted make sure the bush is roughly centred or the lug will break off quickly if the lug is hard against the bracket   needs room for heat expansion

Brand new copy stuff can be variable in quality/life expectancy. Some last well, others fail from new. 

These days I prefer to fit a new one that is branded. Had excellent experiences with the little Denso 40A alternators. Small, light, but about £100 now (or £200 from Brise motorsport)

I've brought 2 replacement supposed Lucas 15ACR Alternators here in Aus off fleabay at separate times they have come in Bosch box's, 12v 34A Part No. 912447 6034-943, imported into the EU by RB (presumably Robt Bosch), one was fitted to a friends TR4 around 5 years ago and works well the other is my spare. I paid under $100Aus each, 

The other one I have as a spare is a South African made Prestolite A127 copy brought from a local motor factor, which was given/fitted to a friends PI and failed after 6 months, he gave it back to me and i purchased a new diode pack very cheap from an auto elect, it was then fitted to the Sprint for 6 months after it's original failed, I rebuilt that original Lucas unit with a new again cheap regulator pack & that rebuilt unit was refitted and has been in 4 years.

Ironically the Sprint came from the chap who has the TR4, both Regulators failed within 3 months, of course my Sprint one failed after I'd given my then spare Bosch/Lucas 15ACR to the TR4 owner!

Whilst I've brought new aftermarket replacement Alternators they have been used as temp fixtures whilst I've successfully rebuilt the original units with new Diode and Regulator packs very easily and cheaply.
