Proper fasteners for heater control

Lets have a look at what you have. The controls bolt to the aluminum (pot metal?)cluster frame.
Could it possibly be these ????? I don't remember what I got these off of.
Your IPB will have a pic.
And what is this magic book of which you speak sir?

So this what I have, and I guess they may be correct, looks like RRA has the same screws, I cant remove the nuts off of mine though.
