Thanks Richard; Sorry - I should have explained I already had the info from the RAVE 'Body Repair Manual' p154
It refers to using a wire cutter or reciprocating blade cutter and I have had a quote of £90 to remove it with the latter.. and so I will remove it 'manually' instead. but I wondered what others had done if/when they had this same problem with this window....
PS: I do have a tip of my own though: And for any car... but quite obvious in retrospect..
When any glass is shattered like this but still in the hole, don't close any doors too rapidly..
or the pressure wave produced blows it all out rapidly too....... doh !
