Yah, the left side only uses 1 bolt and a 'finger' to grab another hole (but it is a fairly beefy bracket). IIRC the right side uses 2 bolts.
If you want something beefier, I could get Welder Guy to fab up an extra left side hitch/frame plate & you can modify that to make a stronger shackle mount.
I found the one that I pulled from Ash's VX. I'll try to snap a pic of it this weekend.
