The GM part is long since gone, I believe they called it a wheel seal. Fiero Store shows to have a kit 65699.

Just to add some context to this, the seal should come with two things, actually. There's a rubber O-ring gasket (that goes between the rear knuckle and the wheel hub) and the seal which is pressed into the back.
One of the reasons why they don't even mention these anymore, is because the wheel hubs are sealed bearing hubs now. Back with the original design, they weren't designed the same way as they are today. You needed that seal in there to help prevent water, dirt, etc., from intruding into the wheel hub bearing.
The replacement wheel hubs for the Fiero are very similar (just different fitment) to what's offered on most cars today, like... my Pontiac Solstice, or my Ford Explorer Sport. Neither of those cars have a rear knuckle seal. The hubs are just bolted to the knuckle with three solid bolts, and that's it. So... you really could do without that seal. For that reason, there are few, if any, parts suppliers that still make that seal because it's just no longer necessary.
That said, it can't hurt, and I had my daughter install new seals when she re-did the rear suspension on her Fiero:
My daughter mentions it at @8:50. I also had her install the dust shield between the hub and the knuckle, which is not how it's originally called for, which is to install it on the face of the hub, between the bolt head and the hub face. It made more sense to put it between for better fitment.
