I'm not a fan of the Skinners for Winchesters. The later angle eject guns weren't drilled and tapped for side mount receiver sights, but the top holes for the scope base is used for the Skinners I believe. With side mount holes, the sight will sit lower.
I don't know if Skinner makes low front sights, most I've seen were pretty tall. I've not had to replace a front sight when using the Lyman or Williams sights. I like keeping them low so they don't snag on things.
If you order a Williams Foolproof, be sure it isn't for an angle eject, they use a monstrosity of a base that attaches to the top, then goes over the side. They are WAY too busy to achieve a simple end, and your gun isn't drilled and tapped for that type anyways.
The Williams 5-D sights are functional, but the adjustments aren't easy to make incrementally. The Foolproof and the Lymans are click micrometer adjustable and easily adjusted in predictable ways.
