They look nice to me. Maybe a bit pricey but that is a lot of steel. I have heard good things about ruffstuff so I would not hesitate to order parts form them.
I see a shackle flip in my future too but I think I'm going to switch to the f-150 leaf springs to gain some wheelbase. Have you considered doing that? I've seen a few people on pirate run 2x4 f-150 springs with a shackle flip because 1. they are 2.5" wide so you can retain your front spring hangar, and 2. because they are 56" long as compared to the bronco springs which are 46" (if I remember correctly) which should give even more flex. If you run them with the double loop end to the front you gain ~1" of wb or if you flip them around backwards you are supposed to gain 5-6". The only downsides that I can see are that you would need an antiwrap bar and you might hit them on ledges when both rear tires drop at the same time. I haven't measured yet, but I think if I do this then I will hang the leafs off the back of 2x4" tubing welded to the back of my frame like a bumper. Ruffstuff carries the parts for that mounting style too.
Anyway, just throwing that out there. I've read about it on pirate but haven't seen it over here yet.
