Stop in for a cup of coffee
Shop manuals will show alignment for crowned roads, manual steering and bias ply tires of the time.
Not many crowned roads left around here, and I set up for comp tires but is close enough for street.
The Barracuda has about 1/8" ride hight, -2* camber, and 2.8* caster, and 1/8" toe in on 25" tires
Your car with street tires and no tricks should ride higher. Maybe a little lower than the book says.
Probably 1/2* of camber will be good with all season radials and 1to 2 caster might be possible. If the slow steering is a PIA then go negative caster. But it will get better tire angles on corners with positive.
