In response to your email, I am very happy to hear about your vehicle. With regards to the yellow plugs, unfortunately, they stopped making the yellow plugs over 20 years ago and we have none. I do have black plugs available. I would require a copy of the original receipt in order to send branded plugs. I have 2 sizes available 3/8” and ½” plugs. I can forward a maximum of 25. If you have the receipt, please forward along with the plug size you need, once received, I will mail them out directly to you. Thank you for your continued in Ziebart.
