Thanks Tony. Hmmm... daunting.
Wiring - no problem. I intend to rewire everything anyway with custom wiring.
The console is history. I never liked it anyway.
The rest sounds like the tough part....
Underdash support bar... hmmm I might can extend the windshield cowl to move the dash out a bit. I've never liked the limited space behind the dash. Since I'll be moving the dash out, the support bar can move out with it.
Ugh - it's going to be a full fabrication rework. I guess I better save this idea for the "dream" car.
Edit - just noticed your URL for your article. I knew I had seen that somewhere.
Looks like you modified your 70's car to fit the early dash. I was sort of thinking of going the other way -> modifying the steel dash to fit the 70's car. Got any thoughts on that?
