So I bought this 68 lemans through a dealer, so unfortunately, I can't talk to the original owner. Here is my situation. I noticed the guy had the heater core bypassed, and wondered why? Maybe the core leaks, maybe the heat don't shut off, so he just bypassed it. but then I got looking at old threads here on the forum, and someone pointed out that you need a seal at the top of cowl, where it meets the hood..... Well, it doesn't look like I have a seal there at all. So now, I'm wondering if this is why he bypassed the core, maybe he had heat coming inside the car all the time from the heat off the engine? Well, anyway, thought I would share a pic with you, and see what you guys think. I probably should order one huh ?
