It has been a bit of time since last update, bogged down with work, kids at home school and lockdowns. I have had the alternator checked (it works) and advice on wiring. This has been installed along with the radiator. While filling found a leak, still to investigate but looks to be the water pump gasket.
Hooked up a battery for a general test. Only half the lights are working with some not wired or broken bulbs. I did find some incorrect wiring at the rear which got both indicators working. Next to look at is the fuel pump. The relay in the engine bay clicks when the ignition is on but there is no sound from the pump.
Found a paint shop that can supply the gold/copper colour, one other was not able to. I got a small sample to test, they supplied three different versions. It looks to the base version that I am after.
Collected one of the 164s that @carnut222 has in Daylesford, for the gearbox, ended up with a second spare engine. Started pulling some peripheral parts off to detail. I have had the exhaust manifolds treated with a ceramic coating, they have come up well (will add a photo soon).
Hope soon to get some time back in the shed to get some work done.
