I do have some great options for you but I don't exactly know the layout of your trailer frame so it will really be up to you to make the best choice for your trailer and needs. That said, I can help with this. I recommend simply selecting a keel roller that is the same size as the existing The CE Smith Deep V Keel Roller Assembly part # CE10405G for example measures 12" long and comes with a mounting bracket that simply requires a set of u-bolts that match your frame.

I have attached our selection of keel rollers and u-bolts below if the above won't work.
