Propane gauge and lock

[spelunkus]

Does anyone have a propane gauge or tank lock to recommend?

I bought a type 1 propane gauge but foolishly thought I could use it after the regulator. It doesn't even fit inside the aluminum housing on a single tank.

Also, I want to lock the tanks down, so I'm interested in any suggestions.

The TorkLift GasLock looks great, and they make 1/2" and 3/8" versions just for AS. However, the one review I found on Amazon says it had to be modified and isn't a tight fit:

Here's a simpler looking one from Battery Shackle:
