Overall good purchase. However it would have been nice to be notified the shipments were coming in 4 boxes instead of us having to reach out to figure out the partial shipments to assure we would receive the full order.

The only thing that would have been better is if the tracking number brought up a map or something more than the order that was placed. Can't wait to install my parts. Thanks.

Hope they’re in stock like the site says!

Great price. Hopefully prompt shipping. Thanks

fast and easy. and good prices
