thanks for the reply, I just could not imagen/imagion/imageon(wow there is a word I just can not get right!) a normal bladed stanley knife being successful.
Ah, you took rear side windows out too, good. I was trying to picture all sorts of twister game moves going on!
Yeah, they probably did not want to help you, as they would rather you get it out unbroken, so that they can still sell it to you. Not often they will help! although, we found one scrap yard the other year where the chap was unusually helpful, even offered us the odd tool to use! Then he ground down one of our sockets for us too, so it could be used with a large spanner, where a normal socket wrench would not fit. (saved us a lot of time and travelling on what was turning out to be quite a large operation to remove some suspension). Then only charged us a tenner. Couple of other items we needed over the following weeks, he did at £10 each too. We now call it the £10 shop!
