    Excellent seller with a fantastic selection of rare classic Ford parts. Communication was easy and responsive, and they clearly know their inventory. The part was described accurately, and the photos were high quality and very detailed. Shipping was fast, and the item was packed with great care. A very smooth and positive experience—will definitely be back for more hard-to-find pieces.

    Well I didn’t read the listing. This is for 1 item not 1 bag of 10. The bag of 10 is the listing main photo. I thought the other photos were to clarify the item In the bag. Nope. Paid the price of 10 and got 1. Will never use seller again. Super fast shipping and excellent packaging.
