I've got around to fitting the alternator - it seemed like an almost direct swap for my old alternator, but I wanted to drop it a bit lower to move it away from the exhaust, so I made some new brackets to utilise the bottom alternator mounting holes on the block rather than the top ones. Pulley was a direct swap from my old alternator.

fitted. I've ordered a shorter belt to give a bit more clearance to the steering column.
