Assuming it's the cossie cortina, all the dizzy drives is itself and the rod out the base of the dizzy drives the oil pump down below.
There may be a blanking plate held with a 1/2" bolt top and bottom, this was to power a mechanical fuel pump on carbed 205's etc, I think irrc this plate would normally be concelled by the power sterring pump brackets on the cossie.
