Thanks guys!
Pretty sure, actually positive they are not the wrong way around - impossible to put on opposite sides. I have just been playing and realized if I lift the starter motor up at the same time as the manifold, I can get them both in position as long as I bolt them both in at the same time - awkward but doable. On the passenger side however not so easy. I am now trying to remove the dip stick that is in the way, but that in itself is hard to get out while the engine is in. Going to need two pairs of hands if i have any chance.
Thanks for the advise on a re-fit slo...at this stage it might just be a better option and can put my time to other areas instead
