[GMaholic]

Hi all... New to the site, and I see how much helpful info / members are here !! Can any one help with opinions on the best fitting door, roof, window weatherstip kits, I need to replace ALL of my door and window seals. on my 71 Blazer..... I have used LEM in the past for a 68 C10, and it fit OK, but was very firm, as it took about 8 months for the rubber to take shape so I did not have to slam doors to make them close. Any suggested Manufacturer, or supplier? PS hers a couple of Pictures of my 2 Trucks, a 76 K10, and My 71 Blazer.
