front shackles not boomerang 3 7/8
frame to ground at door center 23 1/2
I'm sure you understand this, but for clarification since the distinction has come up several times...
Boomerang shackles can provide some additional travel if there's something on the frame that would interfere with a straight shackle, but for the purposes of measurements a straight shackle or boomerang shackle should simply be measured from hole to hole as that's the functional length of the part.
I may get some measurements this weekend, but this week at work has been nuts from being gone for 6 working days and then having half of my crew gone this week. I've also been too sleepy in the evenings to even look at the 4Runner.
