well i got my kit yesterday the 76mm kit and with the meter housing there was a small rubber ring like the ones on the tube but it is smaller,.....what is this used for??? and also on the bottom of the meter there are 3 holes that look like it would bolt to a bracket or something..? do i have to make my own bracket???


i went out and kinda assembled it to get a idea and it was soooo loose on the tb i was like i think i know where that goes
