WHAT SIZE RUBBER DO I USE ON A T25 PANEL VAN?

[jexps]

HI THERE

I HAVE A T25 PANEL VAN 1987. I HAVE CUT HOLES FOR WINDOWS, BUT I FIND THAT THE WINDOWS ARE LEAKING.THE RUBBER SIZE I AM USING IS 6MM.
DOES ANYONE HAVE ANY ADVICE?

THE WINDOWS THAT I PUT IN WERE FROM A CARAVELLE, SO ONE OF THE PROBLEMS IS ALL THE WINDOWS ARE STRAIGHT WHEN THEY NEED TO BE SLIGHTLY CURVED.

CHEERS

If the windows look ok but leak-possibly the easy answer is to reassemble using plenty of clear silicone windscreen sealant--
