Ford 9" wheel bearings - rock auto part number?

ive got a big bearing ford 9 inch that im replacing wheel bearings on. the one i removed is timken U399A. googled brought up "SET20". and googling brought up this at rock auto...

https://www.rockauto.com/dbphp/x,catalog,118,partnum,SET20,d,TIMKEN_SET20.html

it LOOKS correct, and the price is fantastic. but it appears the number on the side of the bearing is different than what i removed from my shafts. some help on finding the right bearing would be nice. the price is half of what napa wants for a bearing that i still dont know is correct, but i dont want to pull the trigger unless someone can give me some input.

Even if you don't buy from them, best thing might be to call your local Carquest/Napa ask if they can look up a number to interchange. Or go in.

thats typically what i do.

we found what i think is the right bearing. but im not sure. now that i got the old ones off, ill be revisiting them. i need to pick up parts anyway.

Those are the correct bearing yes.

i picked up the same part at autozone (timken bearing) for only a few dollars more.

now... my bearings have the race pressed into the housing. that shouldnt be an issue when i replace them with these, should it?

i've always installed them with the race on the bearing.
