Just read back through the Kobra thread and found this image -
I take it you took a moulding from that prototype dash? Bit of work to give it the slightly raised 'pod' to take the Z3 gauges and that'd do nicely.
Also came across this picture -
Anyone know if the fillet panel that runs from the back of the transmission tunnel to half way up the rear bulkhead is structural? (the triangular bit with an oblong hole that looks like a holder for an i-phone on its front face).
I'd be tempted to take the angle grinder to it if it isn't.
