I am replacing my engine mounts, The lower Torque Strut on my car has Part number 05274907AB, I asked the dealership if they had the one I needed based on my VIN and they told me the part was discontinued by mopar.

Every other place I looked it up online says the part number is 05274903AD.

They look the same, and the only difference I can find is a 3 or a 7 at the end. Does anyone know if these parts are interchangeable?

 

Pull one from the yard and see, or take measurements and see if they are close enough to work. I would have them order the part, then pull the unit off my car and match them up in the store.

 

That could very well be an old part number, but they should be able to find the new one that supercedes it. Sounds like either they were just being lazy, or Dodge has actually stopped producing them.
