The following is based on info from various contributors (see table) collated by Tamina.
There are four high-end items of equipment for the Skunk that are uniquely, only available through crafting. Two being available vai random loot drops and two via exploration within the non-DLC systems. All related items can be found located at any time but in order to acquire the equipment, a related mission must be accepted. These missions, offered by station mechanics, will occasional appear in zones until they are accepted. Once crafted, each item must be taken back to their respective Mechanic for installation (or optional sale).
Once all components of an item are collected, they are crafted via "Your Inventory" (Return-2-1-3 through sidebar). Keep in mind that Lock Boxes are fragile and that exterior explosions may nuke their contents too - be gentle with those locks! This short guide gives hints about how to acquire but if you would like full spoiler help, it's available here in Tamina's thread.
The following table describes what's on offer and gives hints on how to find the components. In general, whether Long Range Scanning is required for the Exploration items or not, it can help since related Drop Boxes have different ping sounds and colours to asteroids and ships.
