833 Front bearing retainer

This will mate your trans to the bellhousing, not sure what else you will need to use it the Barracuda, even though I did that in the 70's, better off the shelf parts now hopefully. Might be easier to just buy the correct bellhousing for you car in the long run. No real advantage to use that bellhousing.
