Wow...took those 2 covers off, that was some awkward work w/ the Air diverter and the core cover (idk what they're called). I found a drill and rotary tool were the best at removing those plastic donuts. I AM grateful for not having to remove the entire dash (like other cars), but seriously GM...use screws instead - think about the end user.
I need a new foam seal for in front of the heater core, mine's all wet a messed up. Did you guys just use weatherstrip from HDepot, cuz I can't find a "Heater Core seal" or "heater core gasket" at a parts store. I'm just worried about the temperature of that thing against the generic household weatherstripping.
