Need some assistance chasing down a suspension clunk.

So I recently lowered my ND2 GT RF Miata on GWR progress springs. Installed them, clocked the bushings, drove 500 miles, clocked again, then went in for alignment. All is fine and dandy and i put about 500 more miles on the car. Then unfortunately my lil Miata had a bit of a parking lot incident with a giant truck who didn't see me parked right next to him. His rear tire ripped off my bumper partially.

Thankfully, dude handles it out of pocket and I go to a certified Mazda repair center. All OEM parts, only cosmetic.

Now this is where things get kind of weird and I don't know if this is a coincidence or not. After getting the car back from the body shop, I started noticing a clunk in the front end. Seems to happen when turning slowly on occasion, when the body flexes, and when rebounding off of a hard brake. Also if you slalom in the car aggressively you can get it to "clunk clunk clunk" in repetition. Now I say this might be a coincidence because I'm not entirely sure if the car being sent off to the shop, has anything to do with this sound. I went over their itemized receipt and there's really nothing they should have touched that would have been suspension related and I'm almost wondering if I was just paying more attention to the car since I just got it back from the shop? I don't know.

So anyways, I started investigating and so far I have:

Checked the torque of all suspension bolts

Checked torque of top hat bolts and main strut bolt

Checked torque of strut brace

Checked the torque of oil pan skid plate bolts

Removed BOTH sway bar end links

And even with all of that, sound is still there and I cannot for the life of me figure out what the hell it is.

Is it possible that the sway bar itself is contacting the back of the shock bodies? That's the only thing I can think of at this point.

Looking for any insight because it's driving me crazy and I'm about ready to take it into a shop to have them look at it.

I also contacted the shop that worked on the car and they said that they would take a look. But honestly I'd rather try and fix this myself as I'm not a huge fan of passing off my car to people. Thanks in advance!
