03 ram 3500 heated tow mirror attachment

03 dodge ram 3500 with heated tow mirrors.Had the passenger side glass assembly fall out going down highway.Ordered replacement glass 05086218AA with retainer clip however i need the part that goes between the glass and rotating motor assembly and i cant find a part number or description anywhere.Can anyone help with that?

I highly doubt there are any other parts available.

No parts available for the mirror, you have to buy a new one or find a broken one with the part you need.
