I'm after a coolant expansion tank to suit a 60s car that wasn't originally fitted with one. The radiator on the Jag is difficult to work out if it's a bit full, bit empty or fucking empty. The intention is for the radiator to have a non-pressure blanking cap with a feed to the expansion tank which will have a pressure cap (4 psi) and overflow. The MGB has the ideal thing but I know plastic versions exist (Marina?) and I had one kicking around the lockup from a banger racing experiment. Can't find it of course.

Preferably that's in keeping with a sixties British car. Pretty please.
