411 windscreen and rear screen removal

[Ronald G. Stephenson]

Congratulations on your project and here is hoping that things go well. The seals are likely quite old,and as such, will probably need replacing, unless, of course if the windscreen had been replaced at some time. But, the others are old, dry and be much too brittle re-use. I am fairly sure that new seals can be found, and some member of the club can direct you to a supplier.
As to removal, you will find that a Stanley or carpet knife makes a good tool to cut round the seals to remove the glass. It is very easy to break the glass when pulling it, as any force on the glass might shatter it. Best advice is to hire someone to do the glass removal.
