Guys running no power steering or AC what belt size?

[1986LX2002]

I took off my power steering and AC so now i have just the alt, water pump, crank "duh" and my smog pump. I have the march bracket to relocate the tensioner but I need to know what belt size to run. I bought the dayco belt that march recommended however its too short if I run it over the air pump, so then i few guys on corral told me to run this goodyear belt and that will solve me problems, well that one is way too long. So I have three belts including the stock belt that I cant use and i'd like to drive my car but I cant. And I have to run the smog pump because I still need to go through emissions still so i need to run it, just i'd like to know what belt I need. I've emailed and called march several times and havent heard a damn thing from them so i'm kinda stuck right now.
