i have an 87 t-top and i was in the same boat as you i replaced the doors with convertible doors that have the pedestal style mirrors.it sounds to me that you will need the 87-88 non pedestal style door seal .check with national parts depot they sell these things separate and can work with you over the phone.the t-top frame is the same dimensions the only difference is the trim that overlaps on the A-posts and B-posts.
