I'm building an AIB-1Q kit and am confused about the bridge. It's a hardtail with what seems to be holes for string through or top load.

I'm reluctant to drill string through holes on this one (body is slightly contoured and I've never done string through before- I'll save my first attempt for a flat bodied tele or something) and I'm perfectly happy to do top loading.

Is this bridge top load compatible?
