Reinforce Upper A-Arm Mounts on Sub-frame?

[bigreis]

I have the Grizz Tracks gusset kit in my 09 sub-frame. I hit a small rock going about 30 down a trail and the subframe twisted at the upper a-arm mounting spots. I got it straightened out again (8 ft piece of 1-1/8" cold rolled round bar levered between the a-arms with a ratchet strap connected the rear bumper worked great). Just curious if anyway came up with a way to beef up the upper arm mounts in a manner similar to the lower gusset kit from Grizz Tracks?
