Oh and with all this testing I've come up with another turnbuckle for the upper arm, use part number 36861 the Jammin upper turnbuckle, it's longer and will fill the gap in the arm so it doesn't blowout at the end of the turnbuckle, also another upper arm is also comming which is thicker but i'm still using the 36861 part to better the combo, now if you want to use the outside whole for a different setup, then you would need a new set of arms and use the rear turnbuckles from the Hyper 9 on to the new arms, that set up fill the gap compeletly but that not work on the inner hole that's why you would need two sets of arms.
