Tusken raider mask

[modelmkrbsu]

Need some help everyone. I am building a tusken raider mask this summer and need some help with something. I'm curious if anyone could help me with the measurements of the 4 aluminum parts that come out of the front of the mask, everything you know, or at least the length of the parts. Thanks for your time.
