Chargespeed rear spats - anyone install themselves?
 

Hey all, has anybody installed the rear spats (chargespeed/rexspeed/etc) themselves on the car? I just got a set and it's pre-drilled for the screws and bolts on the top part (that mates with the bumper) but the very bottom piece makes it a super tight fit for space to squeeze in a screw, let alone drill it into the bumper. Wondering if anyone has tips or methods they did to put it on. And no, im not looking to use double sided tape only.
thanks in advance!
