What size head unit pulley did you have before? You just need to do the math to keep the blower turning the same speed.
Get the old ratio, 7.625 / < hu diameter>
Now to get the new size you divide the 7.25 by that ratio.
For instance 7.625 / 3.85 = 1.9805
7.25 / 1.9805 = 3.66
From there pick the closest size they make, smaller if you don't mind over shooting a little, slightly larger if you want to play it safe.
