I just saw that AMD is having a sale on 71-74 B body parts, so I thought now might be a good time to pick up some items I will be needing in the future. Has anyone used any of the AMD parts for 71-72 Chargers, and were there any major fitment issues? I realize that anything I buy will probably need some work, but just wanting to know if there is anything that should be avoided because the specs are too far off.
