Details, process, and hazards to be aware of when replacing the radiator support

Tore the radiator support out of a 2000 year model at jalopy jungle, and deconstructed everything; pulled radiator, trans cooler, all connection hardware, etc. But I cut some lines that went through the support on the driver's side and cut the wiring harness that runs across the front in the interest of expediency. Is there a way to pull and install the "new" radiator support without pulling radiator and trans cooler? And without cutting that wiring harness that runs across the bottom? While tearing the one out at the junkyard I didn't see a plug the disconnect. Also any other pointers on thing to pay attention to when doing this is appreciated. 99 zr2, 4.3, auto trans., 4x4. Thanks.
