I have found that the dash is nearly identical, the pads are interchangeable, but the area where the VIN # is located is a little different. I am going to cut the top left side out of the 79 and weld it in so the vin plate and left most dash pad hold down will work right. The other side seems to be identical except for the hole that holds a speaker which can be used both sides if you use an 81 up dash pad which won't require dash mods except for VIN plate.
