Whilst the lefthand one fitted well enough to the car the righthand one didn't - the top edge was at the wrong angle and pushed it up into the door. You can see in the pic below, there was no gap at all and bottom of the door scraped on it when opened.

It's difficult to capture but you can just make out that top part slopes down too much.

In the end I decided to cut off the top section and then reattach it at the correct angle. I took several measurements along the length before cutting and decided the edge needed to be 5mm higher to be at the correct angle. These struts held everything in place so I could fibreglass under the lip. Once set I then had both sills ready to fit too the arches.
