I think they may have sold out of black now, as no longer showing up on a search!
I'm still waiting for mine to arrive, but I took the grab handle off the passenger side today to make up a cutting template for the roof lining. The bolts securing that are M6x20mm, with form G M6 washers (6mm x 18mm).
