This is the bottom side of the oil cooler. The side on the table, with the angle, will attach to the firewall via the two nutplates and the two nutplates on the top angle, 4 bolts in total on the aft side of the cooler.
Top side.
Here is the angle brace that will support the front end of the cooler. It spans two engine mount tubes and attaches with Adel clamps, one on each end. It needed a twist to get the proper angle to allow the Adel clamp to attach to it.
Installed.
Plenty of room between it and the fuel pump. And there is room to get a plenum on top of the cooler.
How the forward angle attaches.
Underneath, looking up and aft.
