Humbucker Cover Install, Help!!

He there, I have a set of Gibson 490’s humbuckers that I need to add chrome covers to.
I’m pretty sure that I need these Gibson part numbers

PRPC 10 for 490R Neck.. and,

PRPC 15 for 490T Bridge

But I’m just not sure if this is correct.
Im not sure what Gibson part numbers match my pickups’ poles.

Does anyone have any information on verifying which covers fit which pickups? Any information might help thank you!

I don't know if I'm much of a help, but 50's style humbuckers (burstbuckers, 57 classics, ...) have 50mm poles distance on both pickups, while modern-ish styled pickups uses 52mm at the bridge and 49mm at the neck.
