Front Tow Shackles

Here's a picture of the driver's side front tow shackle installed:

The new shackles are incredibly beefy.  They're a direct replacement for the stock shackles, and allow easy installation of D-rings or flat towing hardware (through the middle/forward hole).  Unfortunately, they also add about 1" of lift.  Problems this creates: (1) I'll be 1" over stock in the front but 0" in the rear, and (2) There's now a huge gap to cover in order to mate the leaf spring to the axle, and the passenger-side side brake line (installed by the PO) is too short [correction 2/19: Turns out it's just barely long enough].  I think solution to (1) may be just to put these on the back as well (so 1" all around).  I think the solution to (2) will be just to combine axle reinstallation with brake bleeding, and then replace both lines with longer lines.
