I just installed all 3 new BD seals this past weekend. My van looks and seals up great! I can attest to the fact that no requirement for glue, the obviously high-quality EPDM bulb seal that fits and looks excellent (and should last the life of the van), lack of steel insert clip, plus the ease of installation, makes this choice a hands-down winner in my book. If you need top seals, get the complete kit, like I did. You won't be sorry. Thanks, Ron!
