Thanks IG-88.
I've ordered parts from a number of different vendors so far. I'm really not up yet on who's best for what, etc. (as you know, there's a mind-numbing amount of info out there to wade through). I know that the parts that I ordered will fit in the pre-cut holes in my control panel. That - and price - were really deciding factors...
If there's a specific reason why you're asking about that, I'd sure be interested...
