What's with the two different headlight kits?

So the 3043 kit ($90 with bucket) is a universal aftermarket kit that fits a large number of bikes, may require slight mounting modification, but still looks pretty darn stock. The parts aren't necessarily interchangeable with the factory headlight assembly. 

The 3044 ($100 kit without bucket) fits in the original factory bucket replacing the sealed beam with a lens and a replaceable bulb. The lens requires some modification on our end to fit the stock side-to-side adjustment screw hole in the factory trim ring, hence the additional cost. We made a video explaining how we do it and why. 

In short, you need the $100 one to keep your stock bucket.
