There's a place in Colorado called Jeeps Unlimited in Erie. They are basically a Junk yard just for Jeeps. They get Jeeps in and just pull everything off they have almost everything. And they will ship.
When I bought my jeep I didn't have any either. I found them for sale on Quadratec's site, but I didn't want to pay that much. I went to my local salvage yard and pulled the parts myself for $5 each. Found these for you! Long web address but these are the exact same ones I have in mine, so if you have a flip and tumble they should work.
