Wastegate puck

[driveshaft man]

Can I buy a wastegate puck and shaft assembly for a 3" aftermarket(?) downpipe. My shaft was bent but I managed to get it out without damaging the sleeve in the pipe ..a 5/16 shaft fits smoothly in the sleeve.Its all stainless and no manufacters name to be found on any part of it.Any tips would be appreciated.
