Thank you very much for all of that. It's exactly what I need and as soon as I finish painting the kitchen :roll: I'll see if I've got the raw materials to start on making a copy.

Re the picture with of the upper bracket with the reinforcing strut - very useful. For some reason I had in my head that the strut went at the front of the cover. Seeing it in situ has saved me from trying to cobble something together that was never meant to go there.

Hopefully I have it assembled correctly.. I should have it all together later today. To check alignment, etc.
I vaguely remember reading that you have to be careful with the lengths of these bolts into the engine block... hopefully others will know.... with this bracket it looks like a normal hex bolt will fit, the dynamo bracket had a half height head... I guess a socket head would be a good idea.

Stuart - here are pictures of my mounts in use then a few measurements - if all goes well I might get the engine out after Easter services and can get better pics and measurements, but this may get you started.

The small Denso alternator can be found at a pick-a-part from a Metro Geo, or a Suzuki Swift. If you choose that route, you can grab the plug from the wiring harness that goes into the back of the alternator. Mine for the S2 came from that source, and has been going strong since 2006. Welded up my own brackets, similar to the one shown above.

I used the Nippon Denso alternator also-they are available on ebay although I bought mine quite cheaply from the local supplier.
I used the front lug only of the dynamo bracket and made additional braces from steel strap to secure the front of the alternator-it hasn't shifted since I fitted it 5000 miles ago:

Another approach: Denso alternator installation including a rubber isolator on the adjusting strap.
