Just be real careful when you do it cause it doesn't take much. Have the hooks on hand and take a small bit off each hook slot until the hook fits and the mold close's correctly. Do each one the same way and then try a pour.

If everything went right the most you'll have to do is trim a little flash off of them, but it's usually not that bad.

Good luck and if you need more help let us know.
