Help! Republic Commando Pep Bizeps, Shoulder etc.

Hey guys,
I already started my Republic Commando pep build and finished helmet, backpack, legs and the body.
But i am missing the arm files! I checked nearly everything on the internet: forum + members, contact skip, google search, google search images, but all I am finding are the files for an Imperial Commando build. The files look similar, but there are some differences.
I am in need of the complete arms: handplate, lower arm (not that important), elbow, bizeps and shoulder!

Please give me a hand with this, so i can continue building and share my results with you!

Thanks mates and my the force be with you

Checked them as well, they are slightly different, looking more like imperial commando files.
For example, this is a Republic Commando bizeps:
