I believe you are asking about an equalizer upgrade kit, and we have no way of knowing what is on a 2003 Sunnybrook but can tell you how to determine it. What you need to do is simply measure from center to center of the bolt holes horizontally, and from the center of the equalizer to the center of the top bolt hole; you'll also need to know your axle's weight capacity.

For example, if your equalizers measured 7-1/2" from bolt hole to bolt hole and 4" from center of the equalizer to the center of the top bolt hole, and you had 5,000 lb - 8,000 lb axles, you would use the Equa-Flex Cushioned Equalizers - Double Eye Springs - Tandem Axle - 5K to 8K # LC145546.

I have added a link below to our entire selection of equalizer upgrades.
