As I prepared to mount the tweeter in my 3A, I found that the upper T-nut was loose and not griping the particle board, this caused a bit of difficulty when I removed the tweeter. It appears that the particle board is slightly damaged right where the T-nut goes and I am concerned that I will make it worse by installing the T-nut. My only thought was to remove or bend the spikes out of the way, and glue it in place. Are there any alternatives to T-nuts, or any other suggestions on how to proceed?
