Hey Jeep - just cruised through your build thread.....since your dash isn't hacked up, and if you don't want to do that to mount a DIN sized radio, you could go with one mounted in the glovebox, or build an under dash console like I did with mine. Advice though - if you plan to go floor shifter, do that first, and then build the console around it.
Retrosound makes a shaft style kit, and is about what you would pay for a decent DIN sized stereo - haven't used them myself, but my car audiophile buddy swears by them for the classics he has designed sound systems on.
