Reading the instructions on duct placement in the lower cowling has me confused.

1 -have a constant gap between its aft edges and the front face of the radiator
2 - fit around the center radiator support

Does this mean that the bottom of the duct extends under the radiator? I don't understand the "fit around the center radiator support".

I have an oil cooler, so it would obviously have to fit around those pieces also?

Thanks
