Are those shifters indexed? If it is, does it currently index correctly? Or are you changing shifters?
The original Suntour Accushift indexing system was different from Shimano. Don't know if later Suntour indexing were different from early versions.
To find the correct rear derailleur to work with your shifter, specify what shifter will be used.
