Legendary interiors install question

Most are made to order from what I was told. Seat covers on new cars is a different animal given their snap together channels and such. Hog rings can hurt you. Wear safety glasses when cutting them out. Don't buy the oversized rings just because they are cheaper and dont over squeeze any size hog ring or you'll have the points sticking out everywhere. Then they will attack like barbed wire when you vacuum under the seat.
Row impleted covers like my 67s need to be centered a straight. To have the cover a little bias left on the back and a little bias right on the seat will look aweful where the 2 parts meet.
I aint saying you can't do it yourself but I am saying it aint easy evn with experience. Bucket seats have little rods in them that help create their contour. To make a small loop on one end for hog ring that will anchor the rod so it dont travel lengthwiseis a good plan but you'll need a torch to make that loop. Bend without heat and it will break.
One more thing I should mention is the studs on the tracks. Factory assembly guys had to remove rubber covers from those studs (I have found those in cars before). They can damage door panels, your legs or most anything they contact. I use pvc pipe fittings held with nylon wire ties to cover those studs until the seats are resting just beside the floor holes.
If I think of something else that might be of help I'll type it.
Good luck :)
