Installed mine tonight. No pesky torx on the 06.
Step 1: throw manual out. It's written as if installing 3 separate pieces, not a kit.
The 2 longer 1 1/2 bolts go in the top hinge. Everything else is 1 1/4 length. With the offset brackets installed, i don't see any reason why a 35 wouldn't fit. 37 might fit.
If your tailgate isn't exactly straight, it will straighten out as you bolt the bracket on, lol
Took about 2hrs from opening the box to done. I installed the high lift mount too.
The golden rule of aftermarket parts applies. Assemble loosely, then tighten.
