Stereo in a 72 Chevy 1/2 ton?

[muddpile]

Greetings. I'm new to posting here, but have been a lurker for some time. I recently purchased a 1972 Chevrolet Custom deluxe (I think that's it, not too sure). I haven't even picked it up yet, The guy is still collecting a few pieces for it (he's moving and finding parts for me while packing). I pick the truck up on the 17th and begin disassembly to start my project. I have it mostly planned out, but I'm not sure about sound. I'm an audio enthusiast and have installed a few elaborate sound quality systems over the years, but looking at the cab of my newest purchase has me stumped. There's a gas tank where the sub box goes and no stock speaker holes. There are also a lot of reflective surfaces. What has everyone here done in terms of stereos? It looks like I can just remove the factory radio, modify the dash opening slightly and install the new CD deck correct? What about kick panel speakers, anyone tried them and had great success? I see the dash has a speaker hole in the middle in some of these trucks (I never looked on mine) Is a dual 4" setup in there worth doing? I have done a few searches and seen a few pics, but there wasn't too terribly much on stereo systems in these trucks. For a sub, I noticed someone used a Bazooka 6" bass tube on the passenger side of the gas tank. That looked like a good idea, and I believe the 8's have the same size tube. Road noise is not a factor here as I have a full roll of sound deadening just waiting to be stuck on something. Any help on this topic would be greatly appreciated. Thanks.
