a500 question

I'll compare them when they get here.
I couldn't find anything on either of those other ones ANYWHERE on eBay, google, or anywhere else. Only wrong pix and suggestions for parts with PNs that were "close" (one number off somewhere within the 7 digits)
According to WIT there were 2 choices which they said we're interchangeable. 89 was the cutoff time. This one definitely looks like it'll work, looks alot more like the old one.
I've often wondered why they played with part numbers on any given part so much across auto parts in general.
And the newer ones where the dealer can't tell you anything without a vin where the aftermarket says one part fits all models for 10 years or something like that
