What fastener to use to anchor a small shelf to drywall installed over cinderblock

My basement "features" drywall (not sure of the thickness) laid pretty much directly on top of the cinderblock foundation. There MAY be furring strips behind the drywall that create a very narrow air gap, but it's not much of a gap, if at all. What type of anchor can I use in this situation, to mount a small shelf that will hold knickknacks and things (total weight probably not more than 20lbs). Tapcons seem like total overkill here, but there's not going to be enough depth for a screw-in plastic drywall anchor. Does anyone have any suggestions? Thanks. submitted by /u/yinzerbhoy [link] [comments]
