I apologize if this isn't the right thread. Im looking at buying the DiMarzio crunch lab and liquifire pickup set..

You have the option of getting em for the 42mm or 43mm nut.

Ive got a Sterling AX40 guitar ...http://www.sterlingbymusicman.com/ax-guitars
It says the nut width is 41.5mm Nut Width (1.63″, does that mean the 42 wont work?
All that's refering to is normal spacing/F spacing. I have no idea why it's listed as nut width. Your nut width won't affect the pickup.

Either one will work perfectly fine. I guess I'd recommend the 42 though, since the bridge spacing on that guitar is probably a little narrower than normal.
Spin 'round carousel when your horse isn't screwed in.
