Thanks for the replies guys. I only specified Non-A/C, 3-speaker because that's what I need to end up with when I have Just Dashes "restore" it. I'm pretty sure I definitely need a Non-A/C core, but don't know for sure it's necessary that I give them one that was originally a 3-speaker dash. Also, I don't know if I necessarily need to give them a '70 Challenger core, or if I can give them a later model and/or 'Cuda core that they can make into a '70 Challenger dash pad. I've decided to go the JD route, rather than buying a UR dash pad even though it will cost me more $$$. I am building a show car and don't want to compromise. I have heard countless positive accolades on their workmanship and have seen their work first hand. Also, I live only 30 minutes from their shop, so their won't be any realted shipping charges other than the cost for having a good used core shipped to me. Any other advice is greatly appreciated. Thanks again for all the help.
