78 dash replacement
 

need some help with info on replacing my dash on my 78, please.

Welcome to the forum.
Best advice I can give you is that you will need to get a factory service manual because it requires the removal of a lot of interior trim. You basically have to start with the B-pillar trim and work your way forward so you can get all the way down and get the A-pillar trim off. The dash also has to be very gently flexed to get it out and the same holds true to your new one.
