Over the years we have been asked 'Where can we locate the chassis frame for a Suburban or panel truck?' The answer is not complicated. To save much money General Motors used a modified frame from a pickup. The difference is four right angle brackets riveted to the frame. These provide an attaching point for the large single unit body (Suburban and panel truck).
On most pickups, these frame holes are even punched at the factory so the long side rails can be used for either body style. Therefore, if your Suburban or panel truck needs a frame, your hunt will be less difficult. The attached photos show body mount brackets on a 1954 as they were installed at the factory.
