That's an interesting point David, I don't recall the origin of either of the doors on the Sportshatch, other than they are not the doors that were on it when I got it. The original drivers door is definitely fixable, the passenger side (where the tree landed) perhaps not so much.
When I have a minute I will have a look at how they vary. I recall when I fitted the seals back to the hatch, they seemed similar to when I'd done the job on the Firenza (which also doesn't have original doors, though one is from a Viva E coupe), but that was decades ago too.
So the next question Mike A is - do the seals work in terms of keeping water out? I have an issue on my car with water getting in under certain circumstances.
