Eddie, that is hard to do. The windows on these trailers could change depending upon what was available to use when the trailer was being built. When I finally tracked down some of the seals for my trailer I found that my Hehr Jalousie windows
used some different seals than someone else's exact same model year, make and model of trailer. I would recommend looking at what is on your trailer and compare it to any diagrams showing on the website. One other thing you could do is to look for the model number of the window. It should be stamped somewhere on the frame. Keep in mind you may have to remove trim to find it. Another thing you could do is either order an existing sampler pack of seals that are offered or ask if you could purchase small pieces of the seals so you can verify they are correct.
