HELP! I'm running out of ideas

yeah I measured them, they are 11" across.
i had the new races pressed in and I found dust seal, but they look different than the ones that came off. see below pictures.

The original looked like the first image. It gets pressed in the back of the disc and has a grease cavity.

The second image is what they gave me (both are listed for a 74+ a-body) it fits nice and tight around the spindle but is loose in the back of the disc. Is that okay, does it just seal it when the disc is put on the spindle and tightened?
