Built a bike and used the kit motor mount rear bolts like a dummy. So far the bolts have broken twice and I have had to extract them both times. Here's my dilema, believe it or not I can't find any class 8 metric bolts in this dang town. Been to Lowes, no deal, been to Home Depot, no deal, been to all of the auto parts stores, no deal. As much stuff thats being built in China now a days you'd think these hardware stores would carry a much larger selection of metric nuts and bolts or even all thread rod. Where is the best place online to buy stronger hardware for these kits. I've used the hardware kit from sick bike parts on a few motors but in those kits the motor mount all thread bolts don't look much better than the motor kit bolts. Thanks in advance for any help.
