This is a 300 six engine. So the crank pulley has 3 grooves but it is only using the one closest to the engine to drive the waterpump and alternator. My guess is the middle crank groove will be where the belt goes for the power steering. Does the power steering bracket(s) for the 300-6 interchange with any of the v8 engine?

 

Short answer, no.

 

Long answer = fabrication?

 

Either that or salvage yard.
