Part was exactly what I needed to replace the other one with. It bolted up in the exactly where the other one was. Your product arrived ahead of schedule and was packaged very sturdy. I will buy again from you for parts needed for the CHEVY diesel p/u.

Thanks so much for a speedy sale and delivery process.
