Been a bunch of swingarm buildin goin on so I'll share mine.  Our Blaster's down for upgrades and one of the changes is suspension.   Built it a couple years ago from 2 arms but now changed the shock mount & cleaned it up a bit. Here's the arm set up for ex400 shock.  I used Phragle's info to locate mount holes so I can experiment. Doin the same kinda thing on the a-arms but they ain't painted yet 
  Be awhile till I get this thing all together to test it.
