Are you sure those are OEM [MENTION=175871]gtdan[/MENTION]?
Not 100% sure, but Amazon lists the manufacturer as "Nichibo or Mabuchi". Mabuchi is OEM. I can only attest that it works and looks identical (although every other motor I've seen looks the same too).
I also wanted to order from Amazon so it would come Prime and I could get it done ASAP, since I'm having trouble programming a key fob and moving the lock manually wasn't helping. Plus, I only needed 1 as the driver's door was the only one giving me trouble. Believe me, you won't want to do this for more doors than you have to.
Good luck!
