Well on mine i don't see any bolts to adjust for my car.
Of course you do... its right here... it might be a little tough to turn with your bare hands, but it WILL turn... the first couple time i did it, i ripped some skin
but itll be easier after you get it spinning... be sure to park facing s wall about 30ft... be patient with adjusting it..
Also keep in mind, the driver-side beam was made lower than the passenger so as to not blind oncoming traffic
