Back drum brake locked up

Well my back drum brake locked up on me last night. Took off the drum and it looks like its the brake cylinder. NEV is sold out. Gem parts Direct wants 3x the price. Is there a similar one I can buy from advanced auto?

Looks like the VW “Thing” is similar?

Thanks

This is the part from rock auto.
