Finally got the thermostat and heater hoses changed out. Old thermostat looked like a Motocraft one, might have been original. Went smooth for the most part except one clamp. The heater hoses have these odd clamps on them.

One of the clamps was missing the top half of the bolt. Might have been overtorqued, they were pretty tight. I reused those clamps because they look like a more uniform clamp than the screw clamps. The broken one I replaced with a wider screw clamp.

Put a little piece of 1" hose over the new heater hose like the old one had.

Stopped at Runnings tonight (farm and fleet type store) and picked up R134a on sale for $3.50 a can, Advance wants $8/ea. Also got 2gal of ATF for $20. I can change the transmission fluid and flush the power steering.
