Help - need part number clarification

[Fiddledeede2]

I need to purchase a RHS power mirror and I am getting conflicting stories on the part #. The dealer says it is 17682A. According to the Car Parts Wholesale site, the number is 17682C. They say the C works on Wagon/SHO models and the A works on sedans except SHO. Anyone know for sure before I order it.

Thanks

Sorry I forgot to mention that it is a 94 ATX
