Wanted to update everyone with what I did. Since the hole on the motor is 16 mm MALE, and my OBS sensor is 3/8 male ( that screws into female) the part i bought from speedwaymotors was wrong because it was 16mm male x 1/8 female...so what i did was went to napa and got a 1/8 male to 3/8 female adapter for 4 bucks. worked great. so i basically have 2 adapters on top of eachother and then my sensor, but it works and i can have the sensor so its sticking straight up so its easy to tighten (unlike when its on a 90 degree angle and it hits the firewall when i tighten it)
