Front frame rail interchangeably

[kustomkyle]

Rear frame rails on G bodies are for the most part different depending on what body style you have. Coupe, sedan, wagon/El Camino.

But what about front frame rails? Are they all the same, or are they different per the body style?

Same except for the very front horns where the bumper mounts IIRC

To my knowledge, there are 2 different rails in front, with the difference being length ahead of the forward body (core support) mount bushing. They vary depending on year/carline moreso than body type. I can say that all the Malibus/Caminos have the "short" rail
