I too used the Infinity speakers in the dash. I too ran into the fastener problem. Although, I had an additional problem. The additional tweeter (?) actually stuck up higher than the cardboard spacer ring on the front. When initially installed, the inner tweeter actually deformed the dash. I made an additional spacer to allow proper clearance of the inner tweeter and by using some threaded stand-offs, was able to mount the speakers. They sound GREAT!
