I have Driveline guards on a couple of bikes. They come with extra long chainring bolts for mounting. Details of drivetrain vary though from a bike to bike, so expect that you may need extra spacers for fine-tuning. I have no complaints of any sort - the guards work fine for me. In spite of their price, they are worth the money. If you just wanted to buy those bolts separately, you'd be already up for the half of the price of the guard with hardware.
