Hey man, a while back you told me you had to fabricate your tails that you got from k2motor. Well i believe i have the same ones. Anyhow, could you be specific on how you widened the whole with your file/grinder? did you widen one bigger "ear" so that one bigger "tooth" could fit in...? or did you widen the entire thing and kept sharp edges on the cut? Id appreciate it if you gave me specific details dude. thx alot
