Thanks Savage, the car is not an every day driver and it spends most of it's life in my garage so I'm not overly concerned with frozen doors or leaks from the drip rails delete....I won't be driving it during crappy weather. I doubt that the body is air tight enough that door closing will be an issue. My understanding is that it helps with cooling the interior by improving the air flow through the cab. We had a healthy debate a while ago about filling the vents in the cowl (this is where the ventilation pulls from), bottom line was the air may not be as free flowing but shouldn't be a big deal. After all, I'm in Canada not Arizona. I was going to do the side marker light delete also but was concerned getting it through inspections. Thanks for your thoughts.
