Installing LiquidDarkRP inventory system on regular DarkRP?

[arcaneex]

I wasn't able to find any free inventory which works with Customizable weapons, and to my knowledge none of the paid ones work either so I wish to try LiquidDarkRP inventory system and see if that works
Any ideas how I would go about installing it?

Just use that. It should work.

I did try it.
It did partly work, stores the item but shows errors unless I add or "" somewhere in the main file and even if I do, it shows a crate instead of the weapon model.
