Seals for windows

hi all
can any of the great and good, wise people here signpost me / advise me on where I can get new seals for my mk1 Sportline?
The rubbers that run along the bottom of windows as per pic.

Also I am seeking new covers that run vertical along the a-pillar that cover the edge of the frame.

Please see pics

Any heads up on how to put the window seals on would be really appreciated.

As you can see, my seals are shot and i am concerned that water will get down the inside of the door and rot them from the inside.

thank you very much in advance

Werk34 seems to be the better way , quality seals , perfect fit.

And there is steel inside the seal.

Like the factory ones.

Hi I got mine from vw heritage uk they dont have the steel in like the original ones, but I actually prefer that they are more workable and quite easy to fit.you just cut them to length with a Stanley knife etc .and I pushed them down loosely then used a piece of wood and a rubber mallet to tap them down and seat them properly. Took about 5 minutes a window maybe more I replaced all 4 on my 1990 cabby as they were shot ….Had them fitted a couple of months now with no issues

werk34 and mark carter at classic-vw.co.uk have the metal stiffners both work fine.    not tried the non stregthen type as i found the types i used to be good.. pity exchange rate is so low. as werk34 is germany.
