Just a quick kudos for consolevault.com. My wife and I just purchased a new F350 and I bought one of their lockable compartments for the console. I bought the combination lock rather than the keyed lock based on their advice. This thing is fantastic!! It was expensive though (close to $300 - just looking at it $150 seems much more reasonable). The fit was 100% perfect and it took me all of 10 minutes to install. 12 ga. steel - built like a tank and minimal decrease in the usable compartment space. USA quality comes with a price - I guess I'll (happily) cut them an extra 150 bucks for awesome R&D. They got this thing right. Cheers!!
They have pretty good pictures on their website but here are mine.
