Thanks so much for looking. ***PLEASE PLEASE PLEASE READ MY NOTE BELOW BEFORE ORDERING.*** I CANNOT GUARANTEE SHIPPING ARRIVAL TIMES. THE FREE 3 DAY OR 4 DAY SHIPPING IS NOT SOMETHING I PLACE ON MY LISTINGS SINCE I HAVE NO CONTROL OVER THE POST OFFICE’S DELIVERY TIMES, AND IS SOMETHING EBAY HAS ADDED WITHOUT CONSULTING WITH SELLERS. *** Zero feedback buyers will have transaction cancelled due to ongoing scams. Thanks for looking. All of my items are surplus items and new old stock. I do my best to thoroughly check every piece and describe them as accurately as possible. However, I do get it wrong sometimes and know when that happens, you just have to reach out to me and I take care of everything without any hassle (that includes me paying for return shipping.) Please do your homework when ordering, since I'm not an expert on anything I sell and usually won't know if a part fits anything aside from the internet research I'd do if you have a question. Everything is stored in a pet free, smoke free home. Any product that is DOA or doesn't work as described, I always cover the return shipping for you. Buy from a trusted, 18 year ebay seller with 99.8% positive feedback. I do offer returns, especially if something is defective or not working. But please understand that returns cost money, and shipping has gotten expensive. All items ship same or next day depending on ordering time. I usually always ship USPS priority mail and occasionally first class mail. Thanks!
