What Idler Arm is this?!

Sorry if I'm not too clear It's getting late .( for this old dude)
Yup def looks like a spool type mount to me, If the whole suspension set-up was swapped with the centerlink and all that would require the 73 up idler arm IMO .Hopefully someone else will chime in for a second opinion .
Sorry if My earlier reply confused you, just trying to be helpful.
