I think I missed this the other day.
A tiny bit of progress, been scratching for jobs while waiting for bits to arrive, i've been searching for a Y block thermostat housing but nothing turned up yet, solution was to make one
Started with some aluminium off cuts & couple of hours later I had a housing.
