"will 5th gen JDM mirrors fit on my car"
the answer is a resounding, "no"
unless, like me, you and McGuyver are distant cousins:
basically you need to redrill the door on both sides with two new 1/4" holes, remove all the mirror mounting bolts, sand down their mounts, and one needs to be sanded down about 1/4", also one of the bolts needs to be signifigantly shortened on the mount end in order for it to not poke through the back of the mirror.
I found this annoying.
it also seems as though DX hatches didnt come with the mirror harness than their EX trim counterparts would have...but thats next weeks projects, right now i am waiting for the paint bill after having these colour matched. (it should be obvious from the pictures they are needing a refinish job, anyway)
