Hi Felipe from Chile! I made that rhyme in my head Lol. The width of the nut on your guitar is approx 1" and 11/16" together, one and eleven sixteenths. Actually to be dead on it's metric I believe. The R4 should be what you're looking for. If you don't mind me asking, what happened to the old one? And fyi, 25.5" is the scale length of your guitar in case you were wondering. If you have any more technical questions beyond that just let me know Felipe from Chile!

thank you so much dustincorp

you're very welcome. Do some double checking just to be sure. I've seem a lot of wrong info out there so ya never know. Allparts and Stewart Macdonald are great places for guitar parts.
