Thanks Neil, some interesting discussions on that link.
My leather is dark red (Rolls Royce red apparently) so would blend into the walnut a little too well I think. I am convinced I want magnolia dials to go with the Ivory bodywork and they come with bright bezels so that problem is dealt with.
I assume a piece of thin textured sheet metal would be OK to add, although how do you break the recessed panel out of the dash - it looks like it's epoxied or painted in..?
Onto switchgear. I think the 90s saw a nadir in design and the car is equippned with the ugliest, large black plastic switches ever devised. Anything out there that can act as a direct replacement?
Are Allon White set up for this sort of work as I am planning on having some trim done by them anyway!?
