Difference between side mirror for coupe and the one for sedan

[yeding]

Hi, Guys:
I'm looking for a side mirror for my 99 accord coupe. I can find one in my color on ebay. but it's from a 98 sedan. After a lot of googling, I find out mirrors for 2dr has different part number from the one for 4dr. How they look the same on pic. Do u guys know if they r interchangable or what exactly is the difference? thx
