I'm thinking of replacing the Craig. For radio upgrades all I really need to do is pick up a new DIN bracket from Houston and wiring harness, right? The harness I could probably make since "Mr Buffalochips" is out of them at the present. Any other gotchas? speakers would come later, more than likely. Any cheaper brackets? or old ones for sale that I can cut? (wanting to save my original one just in case)
