I was wondering if anyone could post up a picture of a good quality k-member underside. I found a small block K online that I'm thinking about buying. It looks perfect (no dents) but it looks like it has a weld seam on the under side of it. I was looking at another one that a guy had for sale and it had the same kind of seam weld on the bottom. On both of them it's right in the middle of the bottom side. Is this normal or a repair of a crack?
