On the non A/C power steering bracket that bolts to the 390 engine.
The pulley configuration is:
1. fan pulley- one sheeve
2. alternator pulley- one sheeve
3. crankshaft pulley- two sheeves with space between the two sheeves.
Made two aluminum spacers 1" dia X .800" long that fit to the water pump and one aluminum spacer 1" dia X 1.150" long that fits against the engine block. The three spacers have 3/8" diameter through holes. The spacers were machined on a horizontal lathe.
As a result of using these spacers with grade 8 bolts, the power steering pulley has perfect alignment with the outer crankshaft sheeve.
Do not know if this setup is identical to the original factory setup,
since the power steering assembly was missing some OE parts.
The photos posted by mikeoOoOoO was a big help, since it established that the correct crankshaft pulley was installed on the engine.
