Those are both 1978 Pontiac carbs, but my reference doesn't tell me which one would be for an "L-78" or which one for W-72. I just tells me they are Pontiac carburetor, 1978, 400 cid with auto transmission.
Yes, we have the good pull-offs in stock, $30 each. They are small canisters, and have a straight vacuum inlet, and the restriction is easy to access.
When you get time, call the shop and we'll get what you need headed your way....thanks...Cliff
