It's been a few years since I ordered anything from here but today I ordered a gas tank, sending unit and straps to use under my 72 SB Fleetside and the lady asked me if I needed the seal for the sending unit also, which I did, if not for her knowledge I would have been upset that I forgot to get that too. She was very friendly and with what I've gotten before I'm sure this will be right too! Plus it was cheaper than #####! Whip
