I'm not aware of being able to buy the parts individually, but collegehillshonda would probably be your best bet for a solid answer. The msrp on the hfp suspension is basically a grand. They sell it for $770, but that's also getting you springs as well as shocks/struts.
I don't know if you have a part number visible on any of your shocks still? CHH doesn't list a part number just for the shock itself, so I don't know if that's even possible to get. You could probably get an answer super fast by calling them and asking for the parts department. They are super helpful & extremely knowledgeable.
You could ask for Paul if he's available.
