Door seals/window scrapers

Hi,

Looking for some do's and dont's, Fitting some new door to window scraper seals today and need to know how to do it without making a mess! 89 GTI Cabby by the way.

Thanks in advance

Is that brand new ones? Where from and how much?
As for fitting, just be gentle and all will be fine.
Mine are perished and have been bodged/bonded on in the past. I really want them sorted soon.

No there not new im affraid, cant afford a set of new ones!

Do you just lever the old ones off? Do you need to take the door cards off to get the seals off? Do the seals have clips holding them on, do these just stay in place?

As you may of guessed im new to this…..
