This is incorrect. All 5th Gen Civics / Del Sols share the same outer front door handle mechanism. Part Numbers are different due to different colours, but the functionality is the same. For those who would like to look this up, you will find some Del Sols that share the same p/n as a Civic 2/3/4dr. For example: 72140-SR3-J02ZD.
