My truck listed above 2500HD has weird body mount bolts I need to remove to install nerf bars. They are sorta oblong with a hold in the center, they do not have a regular bolt head on them, see photos.
How do you remove these?

Wow, I can honestly say I never seen one like that. It appears to be missing a few parts. From the picture, it looks like there is a rataining clip holding it in place. Have you taken anything off?

Hi,

What you see in the above pic is not the bolt. There should be a bolt going into the opening with a rubber insulator and steel washer holding the body to the frame. See pic 1.

Here are the directions for replacement. Pics 2 and 3 correlate with the directions.

2. Remove the master cylinder from the brake booster.
3. Secure the cylinder away from the booster.

2. Raise the vehicle on the hoist. Refer to Vehicle Lifting.
3. Remove the park brake equalizer intermediate cable. Perform the following steps:

1. Remove the nut from the park brake equalizer intermediate cable.

3. Depress the retaining tabs that secure the park brake cable to the frame.
4. Pull slightly on the cable from the mounting area in order to provide slack for body movement without binding the cable.

4. Remove the body mount bolts.
5. Properly support the body in the area that the mounts will be replaced.

Caution: When you remove the body cushions, do NOT separate the frame from the body more than is necessary. Possible personal injury and damage to multiple parts may result if you do not follow the guides outlined below:

* Intermediate steering shaft-Do not allow the shaft to extend more than 25 mm (1 in).

* Fuel tank filler hose-Do not stretch the hose excessively.

* Tail/Turn signal lamp wiring/rear lamps junction block-Leave slack in the wires.

* Park brake cable-Leave slack in the cable.

* Body ground straps-Leave slack in the wire.

Lower the chassis accordingly in order to remove the cushions (1) as necessary.
