Ok, I was hesitant to ask this question but can’t find it in the factory manual. I am wanting to level my frame (1950 1/2 ton) on jack stands but what portions of the frame are on the same plane and should equally distant to the ground?
The only section that appears along the same plane to me is the frame under the cab but I’m not certain. Any information is greatly appreciated.

Thanks,
Eric
