Of course yes, I sit corrected
I wonder though if they are factory conversions and strength is added.
So the plot thickens
After I posted this thread I went to town to get an icecream ( were having not normal sun conditions here on the west coast of ireland right now
) and I met a chap with a HSE mini bus conversion . his had rubber fitted windows but I asked to have a look anyways .
Below is the pictures . It seems the converter has chopped off all the bits I was worried about . The door felt solid and he said he's never had any issues
I feel like bonded windows should actually give more rigidity than the rubber ones so hopefully it will work out .
