from what I've seen you can change characters cars and sometimes bodies I've seen people do it with most of the scrapped characters but not the one with the most potential fat abbot I assume because he was cancelled pretty early on
seems that these models have the flattest heads might be the best ones but all have issues
>cartman (perfect amount of detail head is too long and fat)
>grandpa marsh (different vehicle and position)
>mr garrison (glasses not apart of the texture and hair and mr hat being a big flaw)
>starvin marvin (head almost fine but is too skinny to be a normal soyjak/namecaca same thing goes with the body)
