Are Sport side view mirrors different?

[David.X5]

Would appreciate some help -

I need to replace a side view mirror and have a 2001 4.4 with the Sport package I have the auto-dip as well and the memory seats. Mine are not power-fold (I understand those have motors in them and are different).

The problem is just in the mirror base (that attaches to the door) so I transfer over the cover and glass, etc. but I'm trying to figure out if the bases are interchangeable - There seems to be 3-4 different part numbers.

I see some listed as "sport" and some "not sport" but they seem real similar to me. does anyone know what the difference is?


Thanks,

David
