What Idler Arm is this?!

Does your k-member have the spool type or biscuit type engine mounts ?
The idler arm in the last pic looks Identical to My 72 model so one thought is you may have a 73 + spool mount V8 K-member ?
gonna go out and take pics of my engine mount right now. i'm not sure which one it is..here are pics though.
