Question:
I am looking for a dust cap that will fit on my boat trailer. i would prefer something along the lines of a Bearing Buddy. My problem is finding something that will fit. I have gone to many stores and the shelf products are either too big or too small. I have done my best to mic. the outside diameter of the plug I need and it comes out to approximately 2.3125 inches. Do you have anything that will fit?
