Any tips or tricks to taking out a windscreen without damaging the glass? Looked at the repair shop manual it looks like theres spacers and that under the glass. Where can i get these?
Rust has started under the glass. Wish i didnt need to take it out.

Cheers

The best way is to pay an experienced glass fitter. It's not that expensive to pay them to remove/refit glass tbh.
If you're planning to do it yourself, you need to buy the right tooling (which doesn't turn out much cheaper tbh, for a one-off).
