What if you found a welder to fabricate a divider that fits the exact measurements of your trailer? The stud divider would still be intact but but then you would have a shorter divider to work with...that may be a cheaper option that buying another divider from 4 star (accesories can be EXPENSIVE)..
Man if I lived in SD I would totally offer up my welder husband- he loves doing crap like that and he only ever charges for materials and a little time.. He is fabricating up a saddle tree bracket for my trailer tack room ( it was cut out at one timeto make a crummy back tack- wich we have since torn out). And eventually he wants to fabricate a colapsable back tack..
