2 questions

My /6 had a 1 barrel and was replaced with a 2 before I bought it. The manifold wasn't changed so the choke will not hook up. Where can I buy one or do I need to purchase a new manifold? Second There are 2 springs that hook up on the side of the carb. It has an automatic and I can't remember where they go. Can you guys help me. Car is a 65 barracuda that I am restoring and not driven but am making progress.
Thanks so much for your help.
