If you're actually reading the marking on the component, you've probably got it right.
What worried others here, I think, is that circa 1985 components that were large and
green plastic encapsulated components, were a lot of inductors and some capacitors.
That's what made us wonder about this.
You seem certain the cylinder is ceramic, which means to me that you probably do
have a ceramic 2 watt power resistor.
I'll mention this for trivia.
I used to live in a high humidity area, but live in a desert now. I do remember in the
high humidity location, sometimes car components could turn green from organics
growing on some of the electronic components, like a ceramic resistor, because of
the high humidity. If you have a minute, out of curiosity, does this component look
like it's painted green, or could it possibly be organic growth making it look green?
If you're unsure if it's a 2W or a 5W resistor, it wouldn't hurt to buy a 5W one, they're smaller in size these days.
