Another substitute thermostat (for the U20) that I've used is one for a 280ZX.
Its diameter is perfect, it has a jiggler (vent for filling), and comes in the
various temp settings. The Nissan thermostat has a somewhat longer stroke than
most aftermarket thermostats, which provides more flow area when fully open.
