Door weather stripping

[randy500]

And im not just blowing around ideas here. I have been building these trucks for 35 years.
I finished my 72 K10 last year with precision glue on seals, doors shut great. Passenger side not as good as drivers side but no slamming either.
My crew cab has precision push on seals on all 4 doors, they all shut real easy.

All my doors are fully assembled and they did not shut nearly as well when not fully assembled.
I have either new of very carefully inspected door latches and used but carefully inspected striker plates.
I dont have all the rubber bumpers installed in the crew cab yet.
