One of the challenges in a project like this is to decide on the materials, and to get them delivered in time. So I try to order as much as I can in advance to make sure progress is not waiting for a screw that is nowhere in stock.
An even bigger problem is making choices: which knobs on the radio (I ordered 5 different sets....internet pictures just don't tell), what vinyl for the front cover?
I ordered two different 'brick-weave' sheets. One that is 'New Old Stock', meaning it is 35 years old, never used, but almost certainly the color has faded. I got it in white. The other one is newly made in black.
Although the newly made one claims to be according to Porsche spec, it looks close but not identical to the NOS. The embossing is deeper, and somewhat larger hence the bricks look smaller. Material is substantially thicker too: 1.7mm versus 1.2mm. Overall impression is that in the white one the visual focus is on the bricks, in the black one it's more the embossing in between the bricks.
I'll try both on the car to compare (after recolouring with a hobby spray gun in the OEM grey-green)
