#1
I want to replace the trem in my DK2M with an OFR, but I'm a little but confused about which nut I need. I know the size is 1-11/16", but there are two nuts with that size, one is narrow string spacing and the other is wide string spacing.

Nut #3 & Nut #4

How can I figure out which I have on my Dinky?

Thanks,
