Overall room is not so much the issue, you are right though the alty is a bit close, I was trying not to change from the original 300 setup, but might have to.
There is no a/c pump (I wish there was, I'd like one for on board air) but there is a power steering pump, the alty and the pump both sit on their own ally casting, I could remove this and fit the alty over the injector pump, if I do that it'll fit better but I'd be using up space for my panned extra's.
At the mo the alty is 10mm clear, might just see what happens when I fire up the engine, might be ok for the time being.
Dont want an ugly deffy front, I'dve bought a deffy 300tdi if that were the case.
