A Body Frame Swap

[Schwartz Performance]

The wagon and El Camino have the same wheelbase as the 2 and 4 door bodies, it's the rear section of the frame that is different.

I believe the olds and Buick frames are the same. Sometimes bumper mounts were different for certain years, and a Chevelle frame doesn't fit a GTO of the early years.
Just double check the dimension from the center of the rear wheel to the last body mount in the rear. That'd be the only potential difference.

To integrate a 2010+ Camaro IRS will take some fab work. You'll want to see how wide a Camaro is from sidewall to sidewall and compare to your car. I know Corvettes are too wide and the rear cradle needs to be narrower.
