Windshield Sealant Replace Or Reuse Seal

Hello Everyone I Need Help For My '72 Duster Seems I Found Some Leaks Under The Dash While I'm Upgrading Some Wiring What's The Best Way To Approach This Issue
I can tell you assuredly you have a leak at the wiper pivot seals , you’ll see it bubble out or trickle in ..it is a very common problem and update kits are available ( mr. Moparts, Classic, year one , eBay ) you may have other leaks it’s true but for sure the WP seals .
