190 vs 180 Degree Thermostat on 2008 Mustang GT

Ok, just wanted to put this out and see if anyone has some good information. I believe the stock thermostat I have is a 190 degree one. Ford lists two replacement thermostat part numbers. The replacement part number ford lists is RT-1168 which is now 180 degree thermostat. Then ford part #RT-1196 which I assume is 190 degree. Most parts websites cross reference RT-1168 (180) and don't mention anything about part #RT-1196.

My question is, will it do me any harm going from a 190 degree to a 180 degree thermostat. If not, then I will just keep the 180 degree thermostat I got and use that when I do my complete upgrade.

So, after doing some research, and talking to FORD. I found out the stock thermostat was neither a 180 or 190 degree, but a 192 degree thermostat.
