Our records on this one are thin - we don't have more detail on it beyond the catalog line itself, and it hasn't shown up across other catalog listings we track. Given the description names the Gold Star specifically, this is a BSA part, not a Triumph one, despite how it's filed in our system.
If you're chasing this for a rebuild, call the shop and we'll confirm fitment before you order.
