That's not for the first gen G body sport seats, those are for the second version in this image, the 81-84 seats. They look similar but are totally different.
The confusing part of his description is that he's suggesting folks use these to upgrade regular 74+ seats to the 81+ style sport seats with this kit. Nothing at all to do with the first gen 74-80 seats though.
