To fix your clamshell latch.
1. Put some tape around the perimeter of your latch mechanism so that you can remove/replace it into the same location.
2. Remove the latch and put a small thickness washer under the mechanism (under at both screw locations) to lift the assembly slightly.
3. This is a quick-fix and you should NOT use a very thick washer as it will cause misalignment between the clamshell and roof. However, for stubborn closing problems, just this small tweak will cause them to close easier.
Hope this helps.
I agree. The thickness of a single stainless washer was enough to take my clamshell from requiring a heavy slam to closing nice and smoothly. I did not notice any difference between the 05 bumpers and 06 springs.
