67 Cuda bucket seat reupholstery help needed

Yes, there are posts on each seat bottom that hold the seat top from going back to far. There are also the holes in the seat bottom for the attaching bolts for the hinges...those I believe need to have holes put in.
I have a lot of interior photos of Cuda's for research, but the few I have of the lower hinge section show the material bunched up around the post. Just wanted to see if that is how it is supposed to be...
