Well Ian it came about because my heater was shoite/unreliable and on cold snow play mornings I was stuck with a frosty screen!
So, I asked my breaker for a 300 heater screen, 85 quid.
And half of it didn't work.
Luckily got my money back!!
Spoke to my windscreen supplier and be got me a new one for £170.
I assumed it would fit but turns out its different.
So basically (no pics I'm afraid) the 300 has a different aperture because it is a bonded screen as opposed to gasketed.
The 300 has different pillars, which are thicker so that they meet the screen without the need for a gasket. The screen itself is slightly taller so that it meets the roof and scuttle without the need for a gasket.
Therefore, I had a wide screen but pillars that were much too narrow.
I decided to use the gasket but in hindsight may have looked at modding the pillar mounting areas.
Anyway, obviously with the gasket fitted to the new screen it was going to be far too tall because the new screen is oversize to accommodate no gasket. It was also too narrow because my pillars were designed for the wider 200 gasketed screen.
As such, I had to grind the top off the centre areas of the upper and lower body seams, effectively flattening the curve in the body seam when viewed from the front if the car, so that the screen JUST squeezed in. Probably took 5mm off a 10mm seam. Maybe 3mm, not sure.
As for the sides, the screen fitted easy, so we squirted a good tube of not two of sikaflex/windscreen sealer into both sides of the gasket to take up the space between screen/gasket/pillar.
Probably 8mm to take up overall on each side of the screen.
A couple years down the line it has been a great mod despite being an absolute **** to fit
