Making a selection menu and changing player models

So I'm trying to make a selection screen of spaceships for the player to choose from. But How can i replace the player model spaceship each time a different spaceship has been chosen? can't figure out the code. Is there a way to replace the values set for a particular model into values for another model without making different codes everytime? For Example: the score system is set up in a way the score depends on the position of the player in the Z axis. So if i change the player model, can I directly replace the original player model with the new one without writing an extra code each time?

NEED HELP

 

Check out some Youtube tutorials on selecting a character. You have to first understand to fundamentals of an object selection system that affects later game behavior before you can reason about positions and scores and details like that. One thing at a time!
