I'll take them for the price (the 4 for $65, shipped right?). Those are missing the boards aren't they? So the reassembly would require a solder, is that it? They're not really plug-and-play because of that, right?
Yes I do, but I want to see what installing them will involve so let me look that up, or if you like, you can explain to me here briefly. I'll send you my information soon.
