Ed, the retired chem teacher in me will be plotting charts, graphs and results with each experiment ! Only kidding, but thanks for added info for my log. I have a 160 newly replaced thermostat and housing seal which was leaking slightly directly after getting car back from overhaul & new radiator/cooling system. DeWitt's radiator looks like it will hold up to its strong reputation and it does look good! The fan Clutch rebuild/restore by Fred Oliva is Top Flight-Bloomington caliber work. I am curious to see how the system works through the summer. Hope it is a long one here in the Northeast, we need it! Cluster & gauges will be done sometime next Winter. I hope to have them all calibrated & in perfect working order this time next year. Yes the radiator seals were installed, but I will have a look with mechanic/restorer this week. thanks again..bruce 339024
