73-80 Hood Lock and Alarm Questions

[Pyrotechnic]

There's a good chance that the next truck I get with be a 73-80, and I'm well aware of two flaws:

1. Anyone can walk up to the hood, open it, and take or destroy whatever they please. Someone once took my K&N and replaced it with an oil soaked paper filter.

2. All it takes is a slim jim and the door is open. I had some stuff stolen out from behind my seat, just a nice flashlight and some tools but it could have been a lot worse. This was before I had installed my CD player and stereo and it had some junk tape deck in it.

Now keep in mind, my previous truck was not much to look at and just had a stock engine. This new truck will have a high performance 350 and a fairly nice coat of paint, so I would like to invest in protecting it.

What are my options for locking the hood, or making sure that it can only be opened with a pull cable from the inside? Will the pull cable setup from an 80's truck provide good security? I just need to make sure there's no way to just walk up to the truck and open the hood.

Are any of you guys running alarm setups? I'd like it to go off if the doors are opened or if the hood is opened, and probably the sliding rear window as well. I'd also like some way to have power to the ignition cut off when the alarm is armed. Looking for recommended alarm setups.
