I guess anything is possible; it's just a case of how much modification you are willing to perform. While I haven't done the swap, I predict that it won't be a "bolt-in". Things like heater control cables & ducting and gauge wiring are likely to need some modification.I'm interested in installing the metal dashboard from later Duetto or European spider junior into a 1974 spider. Is it a straight forward install or am I asking for a lot of trouble? Is it even possible?
That's right. It's possible that they are the same as a 1750 boat tail.European S2 1600 Spiders had metal dashes ... IIRC until about 79 or 80.
