The build record should be available from Chrysler if you provide the VIN and it will call out the springs by a three letter code. Or if your lucky the paper tags will still be on the springs with a part number but they usually fall off.

And to each their own, quick-struts are bottom of the barrel junk put together by equally dim individuals. Two out of three installations the ride quality was total crap upon autopsy teardown I found parts missing and/or installed backwards/upside down ect.
