I recently had an issue with my power steering pump and needed a new one, I looked basically everywhere and couldn't find one that is for the HR, but plenty for DE. From what i know the DE pumps have a 5 groove pulley and the HR has 6 groove. Was wondering if it is possible to swap the pulley from my one to a DE one, and whats the correct way of doing it. if anyone has any insight please help.

Thanks

DE pump with 5 groove pulley

HR pump with 6 groove pulley

 

Looks like a socket head bolt. I imagine it's probably reverse thread.
