I have a 1978 Dodge Custom D100 Pickup (that being the one with RWD), and you could say that it is the "base" model (No power brakes, A/C, no am/fm radio, ect.) and I was wondering what type of radio I could put in it. It currently has just the plain AM radio which does work, but there are barely any AM stations in my area, so I would like to put something else in it. I know that I could look on ebay or any similar website to try and find one of the other models of FM radio that could have been in the truck, but I would sorta prefer something newer. I understand that there are 1U and 2U radios but I do not know if those would fit in the truck, and if they did, would I be able to wire them correctly. I own two modern type radios that are 1U, but id like to finds out if they would even fit in the truck before I start tearing out the old one, and possibly ruining the dash.
