I just did rear wheel bearings. Bought brand new hubs, bearings, and rear aluminum knuckles.

Dumbass me forgot to put the heat shields on the new knuckles before I put the bearings and hubs in.

Tried to pull the shields off the old knuckles and they're not coming off without a fight.

Appears part numberF189-26-261 is no longer available.

Is there an aftermarket solution? Preferably one that does NOT require me to press the hub out again.
