I recently bought these off amazon for my project, haven't actually installed them yet but the nice thing about this design is they're adjustable for length.
They're currently unavailable but the same type is sold by other sellers I just bought the 30 pack cause it was the best deal and i want to make multiple control panels

You can't really go wrong buying the ones they used on the original machines just the cost stacks up when you're planing a half dozen panels X2 clamps.
