Plastic trim around the edge of the door

Morning chaps.

I'm just rebuilding my Mk1 after a full respray and i've just refit the door seals yesterday but the is a final piece of plastic trim which pushes on along the top of the door and down the back side of the door to help hold the door seal in. It's hard plastic and is an "L" shape. My passenger side one is broken. Does anyone know where I can get a new one?

Also on the inside of the the top back corner of the door is there a little piece of trim which fits in the corner? There is a small round hole there is if it's for some trim but I can find either in my collection of bits and it's been over a year since the strip down.

It's a 3dr btw and is 1982

Cheers
Rob
