For an 1-5/8" diameter bar on your 2004 Country Couch Magna I recommend Roadmaster Bracket for Anti-Sway Bar Split Bushings Item # RMB140 and Roadmaster Split Bushing for Anti-Sway Bar - 1-5/8"
Item # RM205222-10. It is a good idea to check the other bushings as well. If any of them look worn or damaged I recommend replacing all of them with Roadmaster Polyurethane Bushing Kit for 1-5/8" Diameter, Factory Front Anti-Sway Bar Item # RM-4139-127. view full answer...
