MI WTB lower tailgate seal strip for 70 K5 Blazer

[swyfor5]

Looking for a bottom tailgate strip for the rubber weatherstripping on a 1970 K5 Blazer. Mine never had it on there, and I have never seen one, is there such a thing? The rubber stripping is available, but I have not seen the holddown strips yet. I have a real nice top tailgate strip I would be willing to work out a trade on for a bottom strip if available? Possibly the strip that held the rubber floor mats on? Mine are long gone, I do have the rubber floor mats and leveling pads/in rough shape/ but still intact/ if anyone has a interest.
