are all first gen interiors similar enough to where i can swap a full enterior from later years into my 79?

 

I am thinking that most stuff will bolt right in. May get tricky when it comes to the dash. I do know that if you swap dashes, then obviously you will need to use the instrument cluster for the new dash that you are putting in and I am not sure about wiring. I am not sure if the mounting holes for the storage bins are in the SA cars. Wouldnt really be that hard to install them if they werent though. Hope this helps some.
