71-72 Charger 440 HP manifold Choke for AVS Carb ???

[moparmusclecars]

Ok Guys, here's what I'm doing. I sold the original holley 4 brl carb off my 72 Rallye Charger years ago. I am going to run a correct date coded 1971 Carter AVS in it's place. Now I need the manifold choke for a avs carb. Is the 71 and 72 carb choke area on the intake manifolds the same for both years? I was thinking I can just say for a 71 and avs carb and get the right manifold choke. Also, anyone know where I can buy one of these since its a discontinued part through Chrysler? Mitchell has them but they are expensive. Anyone have a source? Thanks Guys
