This is NOS GM part number 364079, group 2.461, which my source says is a buzzer for a 1975 Pontiac X (Ventura) and replaces part number 344836.  As always, it is best for you to verify the part application for accuracy. I do my best, but am no expert. Please remember that NOS does not mean perfect. I try to list every flaw I see, but I do miss some, so if you are not happy, kindly let me know and I will try to make it right. Many of my parts also need cleaning, since we live next to a farm, and they are stored in a pole building. I do not clean them for fear of damaging them by using the wrong product or method. I charge actual shipping costs, including the cost of bubble envelopes if used, but no handling costs, and try to ship within 24 hours Monday - Friday. At times, I may forget to change the weight of an item from a previous listing and the postage may seem high...please be assured I will adjust it if you let me know. I package very carefully and use materials and boxes appropriate for the item I am shipping. I ship USPS priority mail except for heavy parts, and items over $10 I require insurance for both our protection. Items under $10, if you choose not to pay for insurance, I will not be responsible once they have left my home. Please contact me if there is a problem before leaving feedback as I would appreciate the opportunity to correct it. Refunds will be given only if I have listed a part incorrectly. Thanks for looking, and good luck.
