Looking to do a dash swap Building a 87 Buick Regal for my son and wondering if the CTS/CTS-V or Pontiac G6 dash would work. And what is the degree of difficulty to install, if possible.

 

none of those cars are relevant to the third generation fbody Camaros and Firebirds. You'd have better luck on a Regal/ Grandnational forum.

but to answer your question, I doubt any of the dashes in those cars would be an easy swap.
