B-body frame rail (68 charger)

Technical question: Beside the suspension hangers (leaf spring), Are there any differances in the left side and right side frame rails?  Looking at pics, holes seen the same.
Thanks

Yes, they're a mirror image of each other.  Look carefully.  They get narrower (the top & bottom horizontal sides of the rectangle) as they go back towards the rear end of the car, and it's side-specific.

Thanks for the info....I need to replace a rail and needed that specific info.
