Like I said when I bought my t-pro the front bolts where smaller than the rear ones. Also on my front forks the bolt holes/threads didn't go all the way through the forks, so I couldn't put any larger bolts in them. It may be worth looking at the front mounts and seeing if the threads will go all the way through, if they don't then you may need to cut them down, but make sure you cut them properly otherwise the bolts will not thread in properly. I hope I have helped
