Which Specialzed hanger?

[Lien Sdrawde]

I'm (trying) to fix a bike for someone - the rear derailleur needs a hanger, and didn't have one attached for me to compare.

How do I find the right one, as it seems as though there are a few to choose from?

The bike is a Specialized Hardrock Pro, with 3D drop outs.
I think it's about 2004 to 2005 but can't be certain.

A search brings up two possible types, depending upon where the bolt holes are. You've not shown the mech hanger side, which doesn't help.

Plasticine is useful to make a mould of what it'd look like from the frame end at least.

A useful source of all the different ones is here; https://wheelsmfg.com/derailleur-hangers/manufacturers/specialized.html
Their 'Fit Finder' - https://wheelsmfg.com/derailleur-hanger-tech-help - picks out #12 ( https://wheelsmfg.com/derailleur-hangers/manufacturers/specialized/derailleur-hanger-12.html ) or 13 ( https://wheelsmfg.com/derailleur-hangers/manufacturers/specialized/derailleur-hanger-13.html ) as possibles.

@Lien Sdrawde - an alternative is #65 - https://wheelsmfg.com/derailleur-hanger-65.html

If it takes one bolt it'll be this as it's the only other Hotrock listed.
