Don't worry sgrice, I appreciate you trying to help!
I did consider removing those 2 bolts to move the compressor aside. That would probably give me more room to get the top bolt in. However, I believe there are 3 more bolts holding that bracket onto the engine which are underneath the compressor itself, which is a further 3 bolts to remove that. All in a tight space.
Getting the tensioner shaft in won't be a problem with the fan shroud moved up.
