Holley hasn’t put any screws in the holes between the primary and secondary blades in many years.

In many applications, those screws are open to the plenum and can fall into the motor.

Most of the newer design baseplates don’t even have the holes there.

Just use the 6 correct length screws, and leave those two out.
