Yes, I changed it a moment after I posted it, but jjhabs was too fast; I also totally missed the rack eyelets. The bike had been resprayed so the sticker was in question and the other stickers do not appear to be correct. Here is a 80ish 510 with different stickers and lugs.http://www.use.com/5fc79b0c9a51fa3f6d08?p=9#photo=9 Also the 510 has over the BB cabling through 1982 and I'm thinking you probably have to go to 1981 to have no downtube shifter bosses.
