Hanging part's position with constraint connected is not replicating

My goal here is to clone a model that has a constraint used from server storage and the model’s position is in front of the player. The problem is that once the model is cloned to the workspace, the hanging part that has constraint connected stays from where I put it in the first place.

I tried putting a script where the attachments and constraints are added after the model is cloned but it didn’t work.

Why are you trying to hang the Model?
Are any Parts of the Model Anchored?
If it has to hang how about putting the Attachment into a transparent, CanCollide off, Massless Part that you Weld to the Player’s Torso?

Use Model | Roblox Creator Documentation to move the entire model and the hanging part all at once.
