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!
