Did they make different arm rests for different yrs?For some reason the arm rests have a gap at the top of them?The arm rests are from an 86IROC and the door panels are suppose to also be from an 86 but the door is from an 89.Had the same gap when I installed the 86 arm rests on a set of manual door panels that where on the door w/o the armrests.Just seems to be one than after another as I try to piece this back together.
