I used a square plate to mount the rear shackle tube. A greenlee holesaw was used. Wanted a little more surface area for the welds. Some guys use a large washer when mounting a little higher up.
I mounted my rear tube a little lower and back in the rails than most because I have additional holes 1" back from standard in the boxes.
To mount the front boxes, I got a piece of 5/8 cold rolled steel bar, cut a front spring hanger in half, mounted the hanger half on each side. Slid the box on the bar, installed the bar after getting it level and square,slide the box next to the inside rail, level and clamp. Scribe a line around the box, cut out a little short of the line. Might take a few time sliding the box in. You want it snug.
Another hint, cut the outer rails side, not teh bottom of it to remove the bottom and inner sides. You'll never get rid of the edge where the outer to bottom bend is located. If you try to grind it to get flat, you'll warp the outer face... BTDT.
The BBD site has some good directions.
There is a hole already in the outer side rails where the front spring eye bolt would stick. through. You likely have to holesaw the inner panel rail so the bar can go through.

I see two installs that don't look right to me. The first one on the red Duster, whoever installed the boxes, didn't cut enough out and now the front boxes hang below the frame about an inch. Apparently, they didn't cut enough of the framerail out above the box. In doing so, the car is going to have a higher rear height since you can only go so high with your holes for the front spring eye inside the box. Thats probably why that red Duster sits higher in the rear without air shocks and without SS springs - they look like stock springs to me.
The second install in the second pictured car, the box is welded flush on the outside of the frame rail. When I have done these inboard kits, I centered the front spring box under the cut out frame rail, leaving equal distance on each side - maybe about a half inch hanging over on each side and the spring is centered perfectly in the rear frame hanger. Unless you used offset hangers in conjunction with the way you mounted those front boxes, your leaf is probably twisted a bit inward.
Not being a jerk, but the two installs pictured don't jive with me...and I've done a few inboard kits.

Ive seen a bunch done that way. I how ever centered mine.
Just because you've seen a bunch done that way doesn't make it right. That leaf spring has to be plum/centered with the frame rail...if you weld that box in flush with the outside without the offset shackle in the rear, the spring will be twisted. Then you'll wonder why your car goes down the track crooked/funny or sits wierd. It may also affect the spring to unload properly if its twisted.
You can always use a custom wheel (like a 15x10) with the correct backspacing and you can run a big tire in there. Just mounting the box flush isn't going to give you that much more room - maybe a 1/2 inch at best. The only way to get more real room is if you cut the inner tubs out and move them to the outside frame rail.
Just some constructive criticism here...

Not really correct.
It's where you drill the hole in relation to the install. If the spring eye hole is in the same location as the stock perch, except moved inboard 3", the location of the box, up/down is irrelevant. Spring eye hole location is the important issue, not box location except when running certain traction devices. Can't have the spring eye hole too high of far forward in the box..
If you are cutting out the max frame rail, like MP suggests, you better support the rear of the car, it may sag. Leaving more of the stock rail intact, red car or outer rail (my car) you may not have the sag issue. I support them regardless of install method because it's easy and take little time. Better safe than sorry. Seen them installed with out support when leaving the outer in place.
The second install in the second pictured car, the box is welded flush on the outside of the frame rail. When I have done these inboard kits, I centered the front spring box under the cut out frame rail, leaving equal distance on each side - maybe about a half inch hanging over on each side and the spring is centered perfectly in the rear frame hanger.

See my post below. More than one way to skin a cat, plus, I get more well to play with...
