I had a measure up and it seems the problem was the inept metal basher who cut the hole and the fact that the seal has a thicker web than the original.
To be fair I think JK's only fault is that they don't give the sizes and imply that one size fits all and it doesn't. The quality looks good and I'd say it's the seal in the link above
This window is an aluminium framed one and so the aluminium is 3mm thick, bodywork 1mm thick
I guess aftemarket glass is typically 4mm ( anybody know?)
looking at the seal the web is the part that fills the gap between the window and the bodywork, if the web is 5mm like my old seal then the hole needs to be 5mm bigger than the window.
other dims on my old seal are 4mm and 2mm for material and 21mm tall
The JK seal is 6mm web ( or maybe 6.5mm) so you don't think 1mm would make much difference but the inept metal basher has the hole down to 4mm bigger in places hence why it doesn't want to fit. Other places it's much bigger.
I can make the hole bigger to solve that...and repaint it, good job I don't need the van in a hurry.
next problem is I can't find any seals that are 1.5mm and 3mm for the material and 20+ mm tall so I'm torn between...
3mm and 3mm

1.6mm and 5mm

I might give seals direct a call tomorrow and see what they recommend.
Never easy is it
