2004 KJ radiator replacement - no side/circular bushings to swap out?

[ryamkajr]

Doing a radiator replacement on my 2004, from the original radiator (I knowm, right!)

All the how-to videos on youtube showing the replacement process on a 2004 show these circular side-mounted bushings that you pull from the old radiator and place in the new one (along with the bottom mounting bushings.)

My original raidator did not have the side bushings (just the bottom ones), so I assume this is optional dependent on whatever radiator your Liberty was shipped with?. And that they are not needed on my replacement radiator as well since it has holes with a washer nut preinstalled?

Quite sure I had to swap them over from the old rad. I also seem to recall seeing these bushings on other Chrysler products - can't be too hard to source.
