Frame rail interchange

[Catmandu13]

Hi all,

Looking to undertake a massive repair to a 73 Satellite. I'm currently sourcing parts but I haven't found any specs to compare similar rails.

I've found references to the front frame rails of a 73 charger being the same as the 73 Sat, but is there somewhere I can confirm this?

The only thing I know that will swap out is the front frame of a 74 Satellite/RR but the bumper clips also must be replaced

Any help appreciated

No difference between Dodge and Plymouth on the frames.
Factory part manual shows the same part number for both.
