Sure man.
I used thee linkage as well.
You need the linkage, whether you make it yourself or use off the shelf parts(which you'll still have to modify, nothing is "bolt on")
And as far as the folding pegs, with fixed pegs of you lean too far into a turn and your Rearset hits the ground (mounted too low, like passenger peg brackets on a 350) it should fold up.
With the fixed pegs that don't old what happens in this case is that the peg acts as a pivot point and lifts the rear tire off the ground, which as you can guess leads to a wipeout.
I speak from experience here a this exact same thing happened to me on my 350.
