7.25 axle bearings

Damn, rockauto is wrong? I don't even know what's what anymore! Thanks, but now I doubt the info they have for the axle seal that is correct, any idea on that?
I'm kind of doubtful on the shop near me even though they have a 72 dart out front, he said 2 hours to do it if I bring the parts but what are the chances he'll have a tool to press them on right?

Seal is 8660S or WS8660S

PS: I double checked all numbers and fit. I have these parts in stock for a rear I am building. A big bolt pattern 10 brake, 7 1/4 rear with 5.13 gears and sure grip.
