You are right, Jim. There is more room, at the rear bumper area, than near this Body Mount.
The Pass. side, is the same way, but the Box Brace, on that side, isn't rusted.
What I found out, by looking on the Pass side, the Brace on that side, is 1/4" up, from the surrounding metal. Right now, the Drivers side Brace, is 3/4" higher, just sitting there. I 'm gonna tighten the bolt and squish the rubber, down to the 1/4", and weld it.
It's a wonder, I never got the crack, on top of the Quarter Panel.
I work Slow, Don.
I get paid, by the hour.
