I know this subject has been covered over and over again as I have searched the archived threads to see if I could find the information I need, but I could not find a definitive answer to a specific vehicle like mine. With that said, I hope someone here can help me on WHICH POWER STEERING PUMP & PULLEY would have been standard equipment on the following vehicle:

1971 Road Runner (late build May 5, 1971)

340 C.I.

4- Speed Trans

A31 code (high performance 3.91:1 axle pkg.)

Thanks in advance for any information that can be offered

power steering would've been an OPTION
'I believe this (painted silver), from a '72 340 'cuda, would've been the same unit on your '71 340 Road Runner
the last picture shows the pulley offset & diameter difference VS. a 318 unit
