Looks great Dennis. When I rebuilt mine I was amazed at how much better it worked. As you said, if you can get all of the air to flow through the core instead of the dozens of leaky spots, it really does a good job. I put in a new foam seal set, heater core, and plenum. This project gets you pretty good bang for your buck!

And I've had to use it a few times to cool the engine going over a mountain pass in Northern Cali. Nothing like driving in 105 degree heat with your windows down and the heater going full blast!!
