My '61 might not be the same. You need to measure the threaded part. The size socket you use doesn't tell you the size of the bolt but usually a 15/16 socket works on a 5/8-18 nut. Do you have a thread gauge or a caliper to get an accurate measurement? The 18 part of a 5/8-18 nut is the threads per inch.
