Mock up of a BMW Z3 - 507 Hybrid dash. ie in the 507 style but retaining the Z3 instruments meaning there's no bother with speedo, wiring etc.

What'd'y reckon?
Problem is you Ferrero Roche builders have replica dash boards. But us 507 guys have nothing. Just the option to go Ferroro or keep the old Z3 dash. I'm leaning towards rolling my own.
I like the idea of 'rolling your own', but not with the original dials. They just look too 'modern BMW', especially as every model of the period have exactly the same dash and dials so it will still look 1990s.
From what I've seen, the 507 dash was pretty simple, with most of the 'stuff' directly in front of the steering wheel. I would be inclined to have a play with some hardboard and/or flexible ply to see what can be done.
If you can get the dials apart, what about putting (or getting someone to put) new faces and needles on them?
The wiring changes for dials is not difficult BTW, honest. In fact most of the wiring behind the dash isn't really difficult, the hardest part is knowing which wires to use and which to leave, which a few of us could tell you. Actually, no, the hardest part is trying to get a new dash with a million wires and lots of extra hardware to physically fit in the hole (as the huge crash bar is always in the way and that can't be moved).
FWIW I don't think the 'fauxrrari' dashes would look right in your cars, as they are nothing like the original 507 ones.
