Sway Bar Shock Mount Angle
I'm not up on my '68's, and this is probably such a dumb observation that it's going to need to be watered twice a week, but...
#1, those tabs aren't rigid at all and are probably going to fatigue and break if you're driving anywhere close to the limits of that sway bar. They're just pieces of angle-iron sawed off and not braced in any way.
#2, that brake line doesn't look right.
I think if you're gonna spend that kinda money on parts that bolt to your car, spend a wee bit more and get some fo-real 'correct' sway bar tabs welded in, and ditch that mickey mouse ****. I don't know what the '68's used for sway bars. I swapped my '72 over using a complete '74 K and everything just to avoid these kinds of issues.
