The lower end Shimano cants from the early 1990s tended to have those plastic spring bodies. Higher end Shimano cantis were a better design, as were older Shimanos from the mid 1980s and Dia Compes.
Even LX got those plastic spring covers. Not sure if any XTs ever had them.
Quick search and yep, XT had those damn things, too. BR-M737
