Dealer says that I have to buy the entire assembly, can anyone confirm that?

They want $434 for parts. Another $200 to replace it.

The part number is 5099075AA if anyone needs that in the future, that's the part number that matches my interior color (black? charcoal?).

That price matches what I can find online. I have another way to get Mopar parts at cost, so I'll do that now that I have the part number and install it myself. Based on the dealer quote for labor, it must be pretty easy.
