Sighhhh. Keystone in their quest for a bigger financial bottom line went to a type of nail gun about 2015 or 6. You either drill those fasteners out or use a hammer and chisel. To replace that cortex correctly, you just use some self drilling screws which you can find at Home Depot for way too much money or McMaster-Carr. The size McMaster Carr that matches the screws on out '14 is 12x1 and comes in a box of 100 for about 7 bucks plus a few for shipping for the #12 https://www.mcmaster.com/#self-drill...crews/=1bpi9un
