I am trying to get the baffles totally ready for getting them to the powder coating shop. I had to make a couple tweaks. The rear mounting hole on the right baffle was not aligned in order for the bolt to go in so I had to open it a bit.
The 4 inch flange for the oil cooler duct needed a little modifying in order to go with the profile of the baffles. I had to dimple the holes on the baffle that go under the flange in order for the flange to sit flat when it is riveted on the baffle.
I then proceeded to use scotchbrite to scuff the baffle before riveting the flanges on them and getting them to powder coating.
