I have a 307 factory posi. They were made. I found my rear in a junkyard. They had it listed as a factory posi ( they had scraped the truck and keep good records ). We pulled the cover off and sure enough, it is. It replaced my open rear that let go. As to which carrier will fit and which one won't. No idea. I know there are guys here that have added posi's to there 3.07 setups.
