EZ on and Robbins are both reputable companies. The 87's through the 89's came with what was called pinpoint vinyl and had the zippered rear windows and the "wire on" trim strip along the back bow to conceal the staples. Starting in 1990 Chrysler eliminated the zippered window and did away with the "wire on" welting.This makes for a much cleaner look to the top. They also went to a "Sailcoth" top material which is richer looking and maintains it's appearance better. You can use the later style top on the 87 through 89 models with no problems.
Keep in mind that the rear window ( called the rear curtain ) is a separate piece from the top and does not need to be replaced with the top. If the window is beginning to detach itself from the fabric or the fabric is shot then you would replace both the curtain and the top.
