Suzuki 2 Strokes

There are so many numbers for the same rings, it's hard to tell what's what. I need a set of .5mm oversize rings for a 76 GT550. I can't tell if these are right or not. The listed part number is 12140-34031-050. I can find the part number, but it doesn't say what it fits. Just Suzuki. Most other 550 rings are number 12140-34710. Alpha sports and Partzilla numbers don' jive with either one. Can anyone verify that these are what I need?

LINK REMOVED as I found that number to be correct.

hi,just cross referenced the part number 12140-34031 fits ALL GT550's, except if you have Nickasil Bores...which I believe were never sold in the USA,for what ever reason on Alpha Sports Suzuki you add the oversize 050 to the part number it doesn't compute,why I don't know
Cheers,

Dummy me. I kept the old box from the rings I got from Pail Miller. The number is the same as the set being sold on eBay. Just found the box this morning 12140-34031-050. I will get them ordered up directly!
