180 to 210 sound about right

210 is on the high side for a 70's model, back then you had a summer thermostat and a winter thermostat, back then we ran a 165 thermostat in the summer and a 185 in the winter cause our winters were really cold, a lot of days the high was zero. Might just replace the thermostat with a summer stat if your parts store still lists a winter and summer stat. I would not go lower than a 165 in summer and no higher than 185 for summer. If you temp still climbs after a new stat then start looking at the air flow through the radiator, make sure the fins are clean and open, then check coolant flow.
