Jimmi,
I have made similar clips using banding material like on a packing crate. You can but a bend in it and cut it with tin snips and it is thin like some of the original stuff. Do you have any for a pattern? I just took a cruise through the industrial section of town looking for pallets. Take some pliers and snips with you, stuff was everywhere in all kinds of widths so I cut a few pieces for the shop it does come in handy for little jobs like that.
