Questions
Are W01-358-9781 and 1R12-603 the same sample row?
Yes. This catalog keeps one canonical page so the two numbers buyers write do not create two competing URLs.
Do you list a year-make-model for air springs?
No. Send the number on the bag, or the measurements if the number is gone. We will not invent a fitment chart.
