What year did Dodge go to the metric diameter and threads for the lug nut threads on the Dakota trucks? I'm going to Jefferson early in the morning and one of the things on the list are a couple sets of lug nuts. I have 2 different year 6 lug Dakotas here and I'm too lazy to pull a lug nut off each of my trucks to check. One is a 91 and the other is a 96. I know the old 5 lugs were still 1/2 x 20 threads. I'd hate to buy 46 lug nuts with the wrong diameter and threads. Thanks, Gene
