Dash question: '70s dash board same as '68/'69 Cuda?

As far s I know the dash frame will bolt up and welding up the ignition hole will fill the opening HOWEVER, there are some other issues that come to mind. The cigarette lighter is in a different spot on the Cuda dash. I am not 100% sure the cluster and bezel is an exact fit on the right side either due to the lighter being different and the housing using a thumbwheel radio versus the standard knob type unless you have a 70 cluster and bezel as it will have a thumbwheel radio too. Maybe someone with lots of knowledge will chime in either shooting me down or backing up some of my limited knowledge on doing this. Good luck.
Chas.
