i dont think they make one with an opening that small?????
and it will work and perform better with a velocity tube attached, i think 4 - 6 inches is the norm, the uni pod i have in my cfm box has a 2 1/2" opening, you could use a corresponding size pvc pipe, then a fernco coupling to adapt to the carb, or an adapter from here, like i have to go from box to carb.................
