We don't have the room that Steadman's had, so we have to put  the radiator in between the frame rails, so we had to angle the tabs to fit on top of the rails.

We still have the radiator in the flow of  the grill opening, but we will need to shroud this Griffin radiator for a single SPAL fan.

Here is the beginning of the shrould

The lips are rolled over and there are holes in all 4 corners.  They will later be covered with a rubber flap, so when the car is moving down the road the flaps will blow open and let more air flow through the radiator.

When the car is sitting still and the fan comes on the rubber flaps will set flat against the shroud and force the air through the radiator.
