As a matter of fact I am thinking of putting a digital dash in my latest 82 Regal 455 project. Dont ask me why, I guess its just because I have the parts to do it. And I think after a little computing I've detirmined it is a few pounds lighter than any of the analogs. I 've done some dash swapping(two to be exact) and I would not recommend doing this unless you have....
1. Factory GM shop manuals for both vehicles
2. Lots of time, being single is a major plus. This takes a honest 20 to 30 hours to do right because you have to disassemble two cars, reassemble at least one car and than troubleshoot all the problems.
3. Experience with automotive electronics.
4. Knowledge of parts interchangibilty of GM models.
5. Knowledge of common GM manufacturing procedures.
The reason I mention the last two is you are bound to need a part here and there and there are a lot of parts you cant get new. My thinking was I'll just do it the way GM did it when they built the car which is fine but if you dont know whats is exactlly different between the two than if something is wrong how are you going to fix it?
If this didn't scare you than I might part with a digital set up from a 1987 NA Regal with a 3 speed column shift. About $200.00 for all the parts. Thanks Eric Fisher
