When I got the kit from 928 Motorsports, I looked in the parts and in the instructions for the plate along the back of the sump. There was none. This part is in the I-J kit and is critical to making the sump control work.
The first pic shows the plate I cut out. It juts out from the back of the sump and provides an edge for the trap doors to seal against. Otherwise, the doors just stick down and don't impede the flow of the oil out of the sump upon acceleration.
The second pic shows a part from the kit added where it'll be when the oil pan is added to the engine. The doors aren't on it so those two square holes will be filled.
Measured the spacing a lot and I hope it fits snugly to maximize oil kept in the sump. At least, the plate effectively moves the back of the sump forwards an inch so more oil will be kept in the sump and 1 inch further toward the front and over the pick-up.
