1999 Xplorer XLW Sway Rear Bar?

[Roughcutt]

For all you Xplorer owners, does your camper van have a rear sway bar? My Xplorer has a rear stabilizer/sway bar (see pictures) and I need to replace the bushings. However, I'm not the original owner so I don't know if it was part of the original build or added later, or what brand the bar is. The sway bar and bushings attach on the lower side of the same bracket that the rear shocks attach to. Makes it hard to know what bushing to purchase since I don't think this was the the norm for the Xplorer camper van, or the Dodge 3500 Ram Van chassis/9.25 rear axle set up. Any help or suggestions are welcome.
