I am needing an Exhaust manifold for the right side of my wifes Lumina

Does anyone know how hard these things are to find and what the cost might be?
Thanks as always for you guys help.
This is a great forum.

Is it a 2.5, 3.1, or 3.4? What year is the car?

Im sorry.
It is a 3.1 in a 1995 car

By right side, you mean the firewall side or radiator side? I bought the one by the firewall a couple months ago from autozone for $99.99.

It is the firewall side.
I have found a used one for 65$ just not sure if that is the way to go.
Thanks for your time

I wouldn't. I'd buy new, since there's only about a $30 difference. That's just me though.
