Bearing size for shorelander 2012 sx240

[Betik]

can someone help decipher what kind of bearing do I need for my trailer?
This is a picture of the owner manual but I am not sure which one will correspond to my trailer.

I "THINK"

1 3/8 is the inside ...then tapers down to 1 1/16" outside. <-- this is my 2013 Galvanized Trailer.
i bought me a spare hub kit from tractor supply which had the exact dimensions.

you can go to shorelander's website and input your trailer model(on the side with the VIN) and you can narrow down which one fits your trailer. it lists every nuts and bolts. very useful!

I made to Orlando on my original parts but I check the website. It would not hurt to have it for the test of the trip.
