Thanks Izzy

Those elevator covers I did not bother with as I checked on the thickness of material against the gap that I had and found they would rub pretty bad so I left them out, sooner have a small clear gap than two surfaces rubbing together. Also they were tight and that's even before they are painted!
I guess you could try some thinner material but I think the stabs could have been a little wider apart...
Too be honest when I look at mine you don't think 'hey there's a gap there' not really noticeable.
