Is 30 thousandths of length actually going to make a difference? I doubt it! That's maybe two threads on the 3/8" X 24 nut!

Age must be sneaking up on you Jerry. 17/32" = .531". All the ones I have seen have a huge chamfer on the end so a 5 1/2" long one with a modest chamfer could potentially have more threads than original. The threads on the head side are coarse and fine on the top. Most aluminum covers will require them to be chopped shorter if using acorn nuts.
