Hi, sorry for late reply (vacation).
Here is the
bladder
Use a sharp scissor to cu a bit of the DTX bladder
Yes the "bear thread mod" on the upper front and rear arms are a MUST!!!
Use CA glue.. Leave app 4-5mm until the ball"mount" after passing the Y...do NOT, i mean DO NOT over tighten the thread after pasing the Y, it will BIND when mounting then...after everything is done, you will have a "hole" @ the Y fill it up with Epoxy...
If it is worth it? it takes app 2h for all this, and they are ROCK....i have broken 1!! under 200 packs +
