I have 10 unused chrome lug nuts and washers. Not sure what they are for, but the heads have 7/16" stamped on them. The shank is 1 3/8" from the bottom of the lug head to the tip. Washers are slightly fatter than 1/8".
I had a 73 Nova Pro Street car that had a Ford rear in it, and I bought these for that car, but something tells me they were for the front wheels of the Nova making them GM thread size, but I'm not sure.
I'm asking 20$ for all 10 plus shipping, not sure of the make, but the bags had #601-1314 on them. If no one wants them, they are going in the trash. Thanks for looking,,,,,,,,,,,,,,,,,,,,Bruce
