Hey Jake, i got your shims all ready to go, i also went and taped 2 pieces of cardboard together and put the shims between it so they dont get bent out of shape. If those cracks dont open up and you feel comfortable with it, you can do what Phil did and JB weld those areas really good, But with a little twist and added strength, Go to walmart and in the automotive section they sell that fiberglass cloth, cut some of that stuff up really fine and mix it into the JB weld paste and that will allow it to bond better and strengthen it. I'd also scratch up the areas where it will be applied just to make sure it has a good rough bed to hold onto rather than a smooth surface. I'll get the envelope out monday morning.
