Upon fitting the lower supports to the oil cooler, it became apparent that the cooler was tipped down in the front. Probably wouldn't have hurt anything, but looked goofy. Concluded that the bushings on the rear mount were resting on top of the insulation blanket that I added to the firewall, while the supports mounted to the tab on the engine mount and were not set up for the extra distance. I pulled everything apart and cut the holes out where the rear mounting angle bolted to the firewall. Upon reassembly, things appear correct and level.
