Andy, IF you had to mount the bar 1.5" lower( on the bottom of the Kframe instead of through it)-using 1.5" square tubing instead of the flat 1/4" plate supplied--- do you see any drawback?
I do not think ground clarance would be an issue as my oil pan is the low point.
It does look like it would interfrere with the "Jacking" point on the bottom of the k frame.
