There is a small problem.
Here is original post.
Tow hooks
I am the one who contacted the seller two month ago, if they will be able to make one for the Smart. Seller replied that he is not a manufacturer, but will contact his supplier with request. Few weeks later I received e-mail that they have tow hook ready, but looking from description, it is looks like it is made for 450.
Nobody on this forum confirmed or denied that tread on the hook is the same (450/451). Because item shipped from Taiwan, I do not feel like waisting 2 or 3 weeks just to find out that it will not fit.
SmartMaddness might have something similar soon.
