Hoping someone will know the Mopar part number for a 195 degree thermostat to fit a 99 ram v10 2500. It is definitely NOT part number 52028185AC that rockauto has listed in their v10 thermostat lineup. The thermostat I need fits down into a 3 inch metal seal. Its a very odd setup. I am not looking for aftermarket part numbers.
