Hi Leigh,
Your engine bay looks really good, as you know there aren't alot of options for the alt mount.
I solved the issue by making 2 plates from 5mm plate. The rear plate bolts to the cylinder head and provides a top hanger (or pivot) for the alternator. I projected it up to ensure the alternator top hanger point would not rotate.
the front plate bolts attaches to the rear plate with a bolt which passes into the cylinder head. It is also secured using one of the water pump bolts.
this means both plates are each secured by a triangulated set of anchoring points... it will not move.
the lowest point (obscured by the belt) is the top hanger from the alternator.
tensioning is achieved by using a power steering idler pulley (old honda), which can move vertically up and down. this is attached to a plate which also serves as a fuel pump block off plate... thus using the fuel pump bolts to secure it.
this means you can fit it snug next to the subframe rail, where conventional swing out tensioning would not have the space.
the alternator itself is a camira unit which is 60A. Mention camira and you can almost get it for free! I reamed the top mount out to accept the larger diameter alternator bolt which was std on the 308.
The major advantage is a 60A rating in a relatively small compact size.. Be aware this alternator needs an excitor circuit to operate correctly.
the pic is the bracket in rough cut stage.
