does anyone know the difference in size between the door panels on a 78 and the door panels on an 81-91? i want to replace my 78 panels with the new ones. they look better to me. will they still fit the same and everything ? the dash pad looks to be very similar between 78 and an 81-91. has anyone tried this. i really dont like the look of the 78 panels. any modifications that made them look better? let me know, i am very interested. thanks.
