Retro sound

I just bought one for my '72 Duster....it was not that model which (I believe) is for a 70. I bought the cheapest model (Laguna) and it works really well and sounds good. It required no modification to fit my factory dash. Please be aware you should purchase a face plate...the one that comes with it is just a mislabeled rubber gasket. The faceplate required a small bit of trimming to fit the '72...really minor. All in all I like the product I purchased...I went through Crutchfield and they had great customer service.
Hope that helps.
