I recently took on the task of replacing my heater core in my 93 d250 and everything was going good disassembly and reassembly until i started to put my dash back in. The issue I am having is the center of the dash doesn't want to go back under the windshield gasket. I cut the windshield gasket to get all the screws out and everything is installed properly. Stumped me for a few days so I'm seeing if anyone on here has had the same issue when installing the dash. Thanks for looking.
