Re: Inspectors please help! Protrusion from frame perimeter.
 

If the protruding bearings are defining the frame perimeter and pockets are being cut in the bumpers, then the bumper is being mounted inside the frame perimeter, correct? Can bumpers be mounted inside the frame perimeter? Or am I completely misunderstanding something?

dj,
The minor protrusions (including the bearings being discussed such as supplied with the AM chassis kit) are not defining the Frame Perimeter. Major protrusions, structural materials and bearings I linked above may define the Frame Perimeter. In those cases, the Frame Perimeter as determined by the string method, becomes the reference for all the other rules dependent on the Frame Perimeter including bumpers and the 20" extension.

Al,
Thank you! That makes sense.

Gussets on the frame as part of the frame. Total protrusion (with rivet) less than 1/4". Nothing to do the bumper.

Without actually seeing them, I would make a general determination that they would be considered as part of the Frame Perimeter and the rivets would be ignored.
