I realize this is an old topic; but are there still any inserts left laying around? I only now have just gotten to the point where I can tackle replacing mine. I'd be wanting the 700 watts version of course. I see the Lab Standard wasn't made. I guess if I wanted to re-use the Lab Standard ones I have......how difficult is it to take the old ones out? Are they glued down? I'm not hip on ruining originals.
I am attempting to put new ones in some new faceplates I've had for quite a while.
