Part # for Swinger Emblem Barrell Nuts

I need to rescure the Swinger emblems on the quarter fenders of my '70 Swinger 340. I have read previous articles that had link to the part #'s but links have expired. Does someone have the correct part number? I know it a barrell nut for a 1/8" post and 3/16" hole but I am assuming there are multiple based on thickness of the panel they are being used on. Any help would be greatly appreciated.

I did find this description but haven't found a 1/8" stud 3/16" hole #218.
