You can download the ASA tool to look up parts for your montero on mitsubishilinks.com I believe. Thats if you want an OEM woodruff key. A dealer could probably get you the part number too.


I have ASA and couldn't find the woodruff key part number. So I bought a pack of several, did a hardness check and micrometer check (not caliper) and the all measurements were the same 40HRc, 5mm x 9mm x 21mm (3.0l). I was working on a Saturday/Sunday so the dealer wasn't an option.

I would certainly prefer OEM parts.
