When I increased my alternator pulley to 3.2 during my new alternator install, I just picked up a couple longer than I had, from NAPA.(stock lower, 3.5 upper)

Then I brought back the one I did not use for a refund/credit.

NAPA carries Gates belts, with both names on them. They are very accommodating about belt returns(save the receipt). I use the one on 1960 near me, and they always seem to have every size I have ever asked for.

Since you know the size you used before, I would add about an inch and see if that does it. Buy one a little shorter and a little longer than that too, to save trips.
