I do not think I will be using hardened ones. I read on the crane website that if hardended ones are used, that guide plates must also be used. I do not want to use guide plates. I am not too sure what to fill in the form
Open valve spring pressure
Oil holes in ends
And I am not too sure as to the part number to use
