Thanks John,

I did post a list of the key items earlier in the thread, see below. That and the interconnect diagrams should be enough for a proper electrician to come up with a solution, I would have thought. But please don't view this as the "how to". As said before there are many ways this could be tackled or simplified using different switch types and relay configurations". It's just my attempt. Any solution will have it's pros and cons. Deejay proposed a nice push button switch alternative that was a direct replacement for the original PCB switches I believe. This would simplify the conversion negating the need for the toggle switch mounting assembly that I made up.

Not really an auto component. It’s actually from a domestic room heater. However it appears to fit nicely. It eliminates a relay too. Time will tell how it holds up compared to the original 60's radiogram, band changer wafer switch (I did order spares). However it’s switching function is curious, at least to me. It appears to have a double wiper thingy, but works the blower ok. Take a look at my original diagram, I’ve attempted to draw it symbolically. It has no radial stop either.

I also used Altecautotive for all of the smaller pits and pieces. They have a good selection of wire too.
