I have a 2000 dakota extended cab 4x4 auto trans. Where the rear drive shaft ujoint clip goes in the holder it is broken . it looks like some adaptor piece with 4 bolts that hold it to the rear end. Does anybody know what this piece is called and a part number for it? Also is there any interchageable parts and what years they fit? thanks rudy

 

Do you mean the pinion Flange?

 

it is the part on the driveshaft that is on the ground next to the socket and extension as shown in the picture

 

that would be the Ujoint flange

 

The driveshaft flange part number is 5015556AA, the u-joints are both the same number 5014733AB and if you need the bolts, number 6506497AA. These are all mopar part number. Thats if you have a one piece driveshaft. If you have a two piece driveshaft, then you need to replace the whole drive line.
