Repairing Top Catch Threads

One of the screws on the driver's side top-catch was missing so I took off the other screw and measured it to be an m5-0.8 x 16mm. I bought 4 new replacements but on the driver's side they wouldn't go in. It looks like the previous owner once cross threaded something in there and has either damaged the threads or left broken threads in the frame. This could have turned into a major repair but luckily I ran an m5-0.8 tap through the holes and it cleared everything up.
