2.5 or 4in shackle flip

[mtnman210]

I have one of your shackle flips on a truck I purchased from another member here. Is there a way I can tell if it's the 2.5in or 4in version. Is there a number on it somewhere or what point can I measure to tell the difference? I'm sure this is obvious but I haven't dealt with the shackle flip before so I'm curious.

post pic of it we can tell.

or basicly measure the frame bottom to the center eye for the shackle to the flip.
