Car in shop and cannot find needed parts locally. Any ideas where I might locate pulled part which is not junk?

 

Unlikely you will find them locally. Not feasible to get used ones from salvage yard.
Part # 90495585 is available from a number of online sites, and eBay. Just google the part number.
I believe the other part number is not correct.
What is 210192513 ?
If you are meaning the 4 bushings (2 on each side) that are at the rear of the trailing arm,
These are the correct numbers 21019254, 4567244, 90496700. Same part different numbers.
Again just google the number. They are also available on Rock Auto and eBay, also Amazon.
Napa shows them available to order, 2 day delivery.
