I don't know when they changed the design. My first Yak rack that I bought in 1992 had a different style towers. The gutter mounts are different in appearance and function than the old towers and the newer Q towers. I wanted to keep the old style towers when I bought a new car, but they don't make the clips that are needed. Take a look at the new Q towers and you'll see that the plastic "flap" is designed as a sort of cam that the locks lock into. Problem is that if you use too much force ( or a thief does the same) and the plastic simply breaks off.
I had the SST towers on a Volvo 240 and then a Jeep Cherokee. When I tried to move the rock to my Honda Accord, they no longer made the clips for the old SST towers, and I didn't have any luck with NOS or ebay, so I bit the bullet and upgraded to the new Q towers. The old ones were a snap to install. I had more than an hour in the initial instal of the new ones. So now I need to harass yakima for a replacement.
On a side note, my bars are too long, my wife is tired of smacking her head (I of course, would never admit to smacking my head, b/c then she'd "I told you so"). So, to protect her lovely head, and my helmet hanger, what's the best method.
Also, suggestions for best price on a fairing (although yak outta give me one for my woes and troubles).
neveride - thanks for the suggestion that I get someone to help me intall it. I must admit that I'm still not fond of the plastic cam cover or the floppy pads - i think I lost one in the process, dammit!
