Got a bit more finished up on the car today. Here is the final look of the door panel, I painted the armrest and door pocket the dark gray color, not quite sure if I like it but worst case I can just paint it black.
I only remembered to take one photo at the end of one can, I used two cans put the passenger side carpet is now black.
The best find of the day, I was going thru my stash of BMW parts my dad dropped off to me, I have boxes and boxes to go thru, the best one he dropped off to me was this:
From the tag mounted on the spoiler is says: BMW Heckspoiler Type 196038
as luck would have it I was planning on eventually looking for one of these, and I have the old decklid to make a template from.
