Looks like you go hit by the 1st gen's vulerability, where the frames are concerned.
I've seen many of them that took some sort of hit or another and plastered the starter to the block.
In fact, the 1st truck I ever parted out on here was such a deal, took a pop to the nose and killed the starter.
Still have the home made tube bumper off it.
I call it the 1st gen killer.
