The Nun, thanks for that.
<.. you will need a small gap so it doesnt bind and operates freely.>
Yes, I can appreciate that.
I don't recall seeing that gap on our last car, Golf GTI
I think, VW used a flexible 10mm strip that was part of the parcel shelf that sealed the gap?
<My hatch has a gap you can get your fingers in.>
Yup. That's exactly the same space I'm talking about.
<Is the gap a hinderance to you 20mm isnt much?>
No not really.
My wife was sitting in the back recently.
She noticed the gap visually.
She also thought it seemed to allow more noise to get through to the passenger area?
Anyway, it's something we can live with.
We're not intending to put a sheep or pig in the back, like some of these farmers do! :-)
