I have a surco rack that I used on my ZJ. I love the way it looks and works. I contacted Surco if they have mounting adaptors/hardware that will work on the WK2 and they said nope.
Too bad... I really like the way it looks and works. I am thinking of making my own brackets that will make it work on my WK2.
I like the Rocky Road rack as well... if I didnt have the Surco rack, I would have gone with that.
