The original radiator was attached & supported with rubber-isolated side brackets, but the Swift radiator sat on a rubber-isolated bracket at the bottom.
Solution: remove the original side-brackets and join them with a bottom brace + cradle to support the smaller radiator:
I positioned the smaller rad so the original bottom coolant hose lined up. Flipping the top hose over and adding a short extension hose finished the job.
I just need to make an isolated bracket to secure the top tank.
Weight savings: 7 lbs (including coolant). First ecomod done!

This weekend I also:
1) Repaired a sloppy windshield wiper linkage, which was missing a bushing. (The previous owner had "secured" it with duct tape.)
2) Stitched the zipper back on the top of the rear plastic window. It was half off, so the window was flopping around in the breeze, letting in weather & critters.
