70 barracuda Control Arm Pivot pin bushing

Wondering if the Pivot pin in the control arm to K-Member connection should be slightly loose or fully tightened. All new components installed. I have 2 options 1) set everything at ride height and tighten such that the bushing in the control arm does all the flexing while the lower control arm is articulation.( I suspect this is the correct thing to do) -or- 2) leave the pivot pin just slightly lose such that the pivot pin is now allowed to rotate within the K-member itself and relive the lower control arm bushing from the pivoting stress during articulation. Since the pin and K-Member do not seem to be machined as a true pivot point this seems to be not preferred. But it just seems like the pivot bushing itself it taking up a lot of articulation pressure every time it goes up & down. Thoughts?

The lower control arm pivot nuts are the last thing to be tightened after the ride height and alignment are finished

I think the OP is referring to the play in the pivot, The LCA rivets loosen a little bit and causes play. They make stiffening plates to correct that. I did mine, Made a big difference.

Oh

Anlauto went down the right path, I will tighten the pivot shaft fully at ride height and expect the bushing to flex sufficiently for the control arm to articulate up and down

Yes, that is the proper way to do it.
