‘73-‘80 and ‘81-‘91 Dashboard Interchangeability

[JCampbell]

I’ve been operating under the assumption that the sheetmetal dashboards are the same from ‘73-‘91 and that the ‘73-‘80 and ‘81-‘91 dashpads and instrument clusters are interchangeable. Can anyone confirm this?

I’m updating the interior in my '77 to a ‘81-‘91and want to make sure it’s as simple as swapping dashpads and clusters and that I do not need to swap in an actual ’81-’91 steel dash.
