not exactly sure what you mean by cut the vinyl.
I'll probably have to get pictures to explain probably but i'll try and explain
I have both a set of 94-95 doorpanels that are off my car and I have a set of 99-04 door panels on my car.
Where the 99-04 door panels ripple on the arm rest behind the door cup on the 94-95 doors there's that like hard plastic insert rather it being vinyl wrapped like on the newer doors.
My question is of the possibility to use the 94-95 door arm rest inserts on the newer 99-04 doors I have, if by cutting out the vinyl in that area and then inserting the arm rest piece from the older doors.
