Offset shackles

That's a gusset, and I wouldn't cut that. The outboard spring mount to frame rail is already a part of the car that benefits from additional gusseting, which is what the torque boxes do. Plus it only buys you the thickness of the what, 18g sheet metal anyway? If you must I'd grind the edge of the hanger and open up the mounting holes for the hanger a smidge to slide it over, not alter the gusset.

Regardless, the MP kit doesn't interfere there anyway, at least not on my car. The interference is at the top, where the hanger is up against the frame rail. The slight gap at the bottom is because the frame rail tapers from top to bottom.

You're car is slightly different than my '68. The rails on my '68 are much more vertical than yours, especially as it approaches the outrigger/floor support. I also cut the mounts where the lines are below. This eliminated the slight taper issue. Like I said, it's a lot more vertical on mine right at the outrigger and only tapers slightly away from it.

That small overlapped flange was the limiting factor for me. It's not a gusset - at least it wasn't on my '68 (or my '66 for that matter). It's a flange for attaching the outrigger to the subframe. When I cut it off, I replaced it with a complete weld. Plenty of ways to skin a cat. At the end of the day, I was able to redrill the mounting holes 5/8" inward. Doubtful that extra whopping 1/8" even mattered. Probably not.
