Where can I get a mounting bracket for my alternator?  I want to mount it on the drivers side of a left hand drive car.  I can't find one here in the UK.   Bracket is for a Rover V8 3.5 sd1 engine.

What motor?
If Rover you can get it from D&D.

Do we assume that you have the ubiquitous Rover engine (3.5, 3.9, 4.0, 4.2, 4.6).?....or some other engine?
First place I'd check are the conversion/installations in the "photo galleries" at the top of the page for left hand mount alternators...find an installation that appeals and perhaps 'PM' the owner for particulars.
As a last resort, barring any off-shelf bracket(s) availability, it's possible to fabricate a mounting system without too much difficulty.

I have modeled a drivers side alternator bracket for the Rover HRC 2210 heads. It may fit other Rover heads  I sent the step file to Xometry.com where the part was CNC machined using 1018 steel.  I purchase Mild Steel Spacer Bushing 3/4" OD x 1/2" ID off eBay then cut and filed it to the length.  I also have the bolt holes located for the mounting holes on both sides to make your own custom bracket is anyone is interested.  I am using a Delco CS130 for a 1989-1992 Buick Century.  The bushing is 1.856" long.  There is also a support bracket between a water pump bolt and the post on the alternator bracket.


Here is the link to the STEP file.  anyone machining the part will need this

Here is the link to the DWG wile if toy want to modify the design

I believe the same bracket was used in the Triumph TR8 which are more common here in the United States than the U.K.

In the United States, the Wedge Shop (TR8 specialist) makes one to take a GM style alternator:
https://thewedgeshopstore.com/alternator-bracket-gm-style-tr8-rover/

They also sell a Range Rover bracket:

> 7780-14-RL  Alternator Bracket – Rover cylinder head, left side, V-Belt drive, for MG's without air conditioning.

Check with D&D before you order as that may be for a GM style alternator so, like the Wedge Shop version, not a direct replacement.  D&D makes a number of versions that are designed for their MGB V8 swap kit:

7780-14-RL    Alternator Bracket Rover cylinder head, left side, V-Belt drive, for MG s without air conditioning.
7780-14-BR    Alternator Bracket B.O.P. cylinder head, right side, V-Belt drive, for MG s, mandatory with air conditioning.
7780-14-RR    Alternator Bracket Rover cylinder head, right side, V-Belt drive, for MG s, mandatory with air conditioning.
7780-14-BS    Alternator Bracket B.O.P. cylinder head, Serpentine Belt, for MG s.
7780-14-RS      Alternator Bracket Rover cylinder head, Serpentine Belt, for MG s.
7176-14      Alternator Bracket B.O.P. cylinder head, V-Belt drive, slightly lower than bracket # 7780-14-BL.
7780-14-300-L      Alternator Bracket Buick 300 head, left side, V-Belt drive.
