Duster Survivor Radiator Dilemma

I've got the radiator out of the car. I will try to find a radiator shop tomorrow. I'll start by calling the dealer where I bought my Challenger and see who they recommend.

I pulled the thermostat too, and it is the original 195F. It has a tiny pentastar embossed on it. I'm going to replace that along with the upper and lower hoses.

Should I stick with a 195F stat or go lower?

I appreciate everyone's advice.
