Well, I managed to get the screen out with no trouble. The seal was so perished it just fell apart so a gentle push from inside and the screen was in the hands of number two son.
Much cursing and muttering later the new seal was round the old screen and a piece of bailing twine inserted in the other side - we were ready for the next bit.
Offered the screen to the hole and with a nudge it settled back enough to get the seal over the lip so that the twine could be pulled. We aborted this attempt as the screen was too much of centre. However, our confidence had grown as we could see how it all worked.
Offered up a second time (much better) and pulled and pulled. The screen settled back nicely. Smugly we tugged the twine for the last couple of inches. Yep, Autoglass come tomorrow with a nice new tinted screen.
Well at least we tried!
Regards,
Richard
