just as long as you tell what ship it's for there probably won't be any problems. i mean the hardpoints are yours, and you're not taking credit for anything else. If you feel insecure, just tell who made the ship you're hardpointing then no one can say anything.
Yuo don't need permission for a hardpoint.
But if you want to post the model as well, then yes, you will need the authors permission.
