I'm told 964 lower covers are a bolt-on, except that the actual stud holes are 2mm(? - think they're M6 instead of M8) narrower. Of course, they already have the lower plug holes.

Now that's gotta be easier with home tools....

I've heard some people say they prefer the smaller plugs in the bottom - some say it leaves more metal in the head, for better heat dissipation. I've also heard people make dismissive noises at this.

Pick your expert and follow their advice? Both ways seem to work though...
