Interior Door panel questions ? 70 series

[In2cruisers]

I've noticed there seem to be a couple different types of interior door panels..some are arm rest type and some have a vertical grab handle...reason for differences?. Years? And are they interchangeable? My rig has the arm rests.. But also have two yellow plastic retained screw receivers

there just different spec trim the door shells are the same you can use either type cards and armrest/handles, when I replaced both of my doors they came with armrests and swapped them over to my basic cards with pull handles
