Steering suddenly hard right - What????

My daily is a '77 Silverado.

Today, my truck is pulling hard right - so much so that I got out and checked the tire pressure expecting to have two full flats. Tires are fine. I have to steer with the wheel turned about 60° to the left just to go straight.

The truck did NOT do this last night when I parked it.

I'm thinking something is wrong in the power steering box control valve.

Any suggestions on where/how to diagnose this further?

Thanks!
