According to Mr. Proctor, the GM website does not have the information.

The GM Collision Repair Center looked in the Chief Measuring System database and the frame specs in question are there, but GM has no way of knowing if they are correct or not. The complainant told us they fixed the truck using the Chief data. Just to clarify, GM does not publish frame specifications. Mitchell International, San Diego, CA, provides these specifications, using their own measurements. Please note this is not an issue of Service Information being with held from the aftermarket. We do not publish frame specs to the GM dealer body; they get them from the aftermarket equipment suppliers or service information providers, just like aftermarket body shops. The frame rack equipment suppliers using their 3-dimensional measuring equipment provide dimensional measurements. Mitchell International also provides point-to-point measurements. GM does not send frame specification information to equipment suppliers, but rather invites the three largest measuring equipment suppliers to the Tech Center at least twice a year to measure and develop their data for our new vehicles. The three are: Chief, BlackHawk, and Car-o-liner. The only place to get the frame spec data is through the measuring equipment suppliers. In order for a shop to repair a vehicle correctly, 3-dimensional measuring equipment must be used. The measurement data is provided by the measuring equipment supplier with the equipment.
