how hard is it to cut passenger seat into a bucket? anyone ever tried this at home without an upholstery "pro" working on it. i have little to no experience working on upholstery but im a pretty handy guy and would love a new little project like this....will i need to get new foam for the bottom or can i rework the old one? i have brand new upper/lower covers for the drivers side but the foam is totally ruinned so i will need new foam for that aswell...where can i get these?
