Power Stearing Fluid For A Ford Mustang 71 Advise please

[chevy 1]

Can Anyone Please Tell What Type Of Power Stearing Fluid Is Safe
To Put In My 71 Mustang .

The System Is Empty At The Moment , Ive Got Confused With ATF AQM whatever.

[57ford]

Castrol Type F transmission fluid. It will say on the back of the bottle.

[Briz]

Any Automatic fluid is fine. Dexron is slippier than type F; might help a bit.
Not that critical.
