Unusual kitchen faucet mount

[Creaky]

I'm attempting to replace an old faucet on an undermount sink with granite countertops and can' t get the old one off. I have replaced several faucets before but have never seen a mount like this. It is a single hole installation and is a faucet with a pull out sprayer. I attempted to turn the black nubs on the end of the threaded bolts and they just came off as you can see in one of the pictures. This left a flat-bottomed bolt. Not quite sure how to remove this without using a Sawzall. Can't find a model number or brand name anywhere on the faucet. Any help would be appreciated!

It could be accessible from the top. Post a picture of the faucet

Pictures are not great, but it looks like those two flat cams lying outside the faucet mounting hole should be able to spin about 180 degrees, hinging on those mounting bolts.
Then they would be inside the mounting hole, and everything can pull up and out.

You pbly have to get the sprayer hose out of the way first, it should just pull out from one end or the other.

The flat cams were likely held up tight by the black nubs.
So the flat cams should be able to drop down now about a quarter inch, then rotate inside the faucet cavity and bingo the sucker comes out.

Once the sprayer hose goes away to give them room to swing inside.

Here's a picture of the faucet. I pulled out the plastic filler from the back of the handle to see if I could access a screw or some other type of access point to disassemble the faucet from the top down and was unsuccessful.

Great suggestion! The black nubs were threaded opposite so I just had to turn "righty loosey" after removing the spray hose and BINGO! Thanks!

I had the same issue. I was totally stumped. Thanks!
