I bought "conversion kits" which supposedly do the job in 5 minutes, but the I discovered that the kit is designed for the current type of can, and is not suitable for the ones that are up there (22 years old). So I decided to remove the cans completely and patch the drywall. After removing the can there is still a mounting bracket up there, which seems to be firmly stapled to the adjacent 2x4, and looks as if it is too wide to go through the 6-inch hole. Do I have to cut a much larger hole to get it out, or is there a secret way to collapse the bracket in some way? I cannot access these from above.
