So I'm looking into making a ballast box for my ck35. I pretty much got it narrowed down that I will make some forms and pour cement. I'm just looking for ideas here but, is everyone using a drawbar for the side links? What is everyone using for the top link? I know there are many options. Like I said, I'm just looking for ideas. Do I need to add rebar or will it be ok with no rebar. Thanks.
