D24T bellhousing.... for an automatic ZF transmission?? or for a manual M46 transmission?? Or something else, like a Pinzgauer or VW LT van or AMC Gremlin or Porsche 924 or Audi 5000 or VW Transporter truck??? All of them share the same extremely common Audi 11-bolt bellhousing pattern. There are probably a dozen or more types of "D24T bellhousing" that exist, depending on vehicle and transmission type, so we need help understanding what you are looking for and what you want to do with it.
Are you looking for one out of a Volvo car? Or just any D24T pattern bellhousing, like this one?
