it's next to impossible. : \

Alternator Grimlock is about 3 years old already. Due to a huge boom in TF interest because of the movie and a very popular (yet cancelled) toy line ... Grimlock (and his repaint Wheeljack) are pulling $100-ish.





There is an all metal, JDM Alternator, by the name of Binaltech. You might be able to find that in the area of $60 shipped (msrp $50) if you're lucky. : \
