That is probably one of the best in-dash mod's i've seen yet for a cat.
I just recently purchased a 99 cougar, and I'm looking to do something pretty similar to you. Where did that other dash console come from (in the last pic of the 2 side-by-side)?
Also would you mind sharing which paint you used? did you paint the whole part or just around your mods?
Do you have any finished/installed photos? I'd love to see them.
