i have them and a gsxr back brake setup u gota make some brackets for the shifter side i drilled a hole in the heel gurad and monted to the holes that were already there for the stocks ones and the other side i made a bracket outa some metlal i got from the hardware store
my sons blaster i put the yfz's on, with my brakes, just bolt to the peg, and make 2 small aluminum brackets for the top rear mounts, in this pic, you can see the mounting loop sticking up outta the gaurd, and the frame tab beside it, just need a short bracket to connect the 2
i lucked out and found brand new in the package yfz's on ebay for $20 + shipping,
i can get pics later tonite when i get home, or possibly even make you the brackets if
needed
the shifter side is just a small L bracket, the other side i had to change to go straight up to the fender mount, when i had it going sideways to the heelgaurd tab, it started bending down from my foot slamming it when kicking
