Part ID help

[JKZ27]

I recently found these shackles in a box of parts as I was cleaning out some stuff. Do they look familiar to anyone? There stamped "Foxcraft LK-51". Thanks for any help.

Hi John.

Those were originally rear extended shackles for tri five Chevys, but yours seem to have been modified / cut down; they are supposed to have 3 different hole spacing options, 6&5/8, 8&1/8, and 9&5/8.

Hope this helps.

Cheers,
Anthony

Anthony, that helps a lot! Thank you.
Didn't think to look for cut marks.
