Hello Mark,
Have you any further movement available on the radiator? I can see a bit of daylight where you’ve got some foam padding at the front. You don’t need much in the way of clearance and in this situation and I’d also be looking at whether you could get more lift if you modified the top mounting arrangement. You might also have to modify the ends of the pipes. I was also shown recently an example of silicone radiator hose that had a significantly greater flexibility than the tough rubber ones traditionally used. With various nips and tucks you might be OK.
