Actually, I did clean them as well as they could be...Michigan salt just ate them up to bad....and re-lubed them. It's just that they are so bad that they will end up causing the problem once again. This is the third set of pads I have done (2 for the front) and none have ever come with the clips. Wonder if I can get them from the dealer???
Go down to Autozone (or your local shop) ask to see the pad they have to choose from (cheapos thru most expensive). I'm betting you'll find a set that comes with the clips. You've probably been getting the best price pads previously (one reason they cost less is the absence of clips.... some are exactly the same pads with or without clips, offered by the same company but labeled as "standard" vs. "deluxe" or words of that kind).
Then you can either buy on the spot, or at least be aware of which model "name" comes with the clips so you can order on line if you must.
Your on-line info should indicate if the do or don't come with clips, but the most sure-fire way to know you'll get them is to make the trip to the parts store.
And yes, you can probably get them from the dealer, but unless you're really short cash, you're going to get a much better deal buying your next set of pads now with the clips to 'steal' for your current pads.
And if you really have that much corrosion, you might want to have a professional go thru your brakes to clean & lube. I'm not encouraged by your description of your DIY process. Did you actually pull the pins (they screw in) to lube them. If you have corrosion inside this pin/cylinder area, you really need to get new calipers, IMO.
You might also want to check out some YouTube videos on pad replacement... after the tire's off, you really only need to remove one screw to get to your pads iirc, and then a little more work to check your slide pins of course. (what are you doing with the screw-driver & pliers ??)
