Epiphone grabber question (humbucker version)

Hey guys! So, for those of you that got the epiphone grabber with the MM-style humbucker (not the G3 Mike dirnt signature), what are the measurements of the pickup cavity? I'm on the verge of getting one, but I've heard mixed opinions of the stock pickup, so if anyone knows the measurements of the cavity I would be incredibly grateful in case I would want to drop in a replacement pickup. Depth also matters, because I've been curious about trying a more boutique brand. This particular brand's pickups are a bit bigger than the standard MM style pickups depth-wise because they're multicoils.

Thank you guys, would really appreciate any answers, or even recommendations for pickups I should take a look at.

Cheers!
