Are mobile home sinks different?

I just bought a 1977 mobile home and have a clogged kitchen sink. It's a double sink and the water comes up from one side to the other and now they are both clogged. It has a weird looking drain (white rubber) with a few small holes, so an auger wouldn't go down that. Any ideas? Thanks.......

Pull the trap below and snake from there. Yes they often are different.

drain

No drain fitting has openings large enough to snake through them. You have to disassemble the drain piping. They are not always different as much as they are almost always the least expensive available.
