This time i need to know how to get Leader Class Movie Optimus Prime's arm into vehicle mode.

Also how to get Cybertron Snarl's wolf head to fit perfectly i cann't get it to fit perfectly in his wolf mode?

 

Can you be more specific on snarl?

It might be one of two things. Are the arms in the right position(Up or down) including the one arm that begs in the wolf. There are also begs in his neck. The upper front paws have holes that connect into them.

 

With Prime move his arm so that the shoulder is straight up and down then his upper arm should be at about a 20 degree angle. making it as close and tight to his body as it will go. then just angle the lower arm so primes fist is in the air and the arm should make a nice side panle., then put the shoulder armor pannel thing in place and you have a alernate mode arm.

Edit: Heres a link to how it should look.

 

For LC Prime its so easy. Just make sure both his arms are in an "L" position before you fold it backwards. It also helps to remove the blaster from his arms first. Go to youtube.com and find videos from matrixprime. It will help.

Happy New Year.
