Perfect fit and fast shipping.
This device shipped REALLY FAST, like two days, and allowed me to finish my install and use my car for a trip when I thought I would need to use an alternate. Another part I bought from 1A Auto also shipped REALLY FAST! Because of this, 1A has become the first place I look for replacement parts. Their prices were the best, too!
