Hello, I'm new to this site. I have a 1989 Firebird Formula with a 305 engine. I'm looking for the right side emission tubes that connect to the exhaust manifold. Does anyone know where I can buy these?

You might have better luck just buying the whole manifold, and swapping that in. Here's a set on ebay, price isn't too bad:

If you are talking about the A.I.R. tubes - Rock Auto.

Have fun installing the damn thing!! (Stub wrenches help)

I found the part there, nice site to know about.
