AC Delco shackles

One of my ESPO leaf spring shackles broke off. Don't know how as the shackles are new (2 months old) and the car has not been driven a lot since install. Anyway I ordered 2 new shackles from online (AC Delco) just in case ESPO might have another bad one lurking in the pile. To my surprise they are the same in every dimension except for width. Should I be good to go or is this going to cause me a problems?
