So I took the windscreen out this afternoon, wasn't sure if I would get the time so didn't get mr raider round to help, spent an hour with a Stanley knife cutting it out as it's gonna be the only original glass to go back in, well that was the plan
So had it all free, so I thought, lifted it out about 2" and crunch, a crack appeared in-between the inner and outer glass, the bottom left corner was attached enough to create enough pressure to cause a stress fracture.
Any way the good news is it's all solid, the bubbling around the screen was between the original and new paint and no sign of rust at all. The rust spots along the top edge are gonna be a simple fix also.
Now with the knowledge it's good around the screen I'll set about repairing the sills and replacing the front end
