I cannot remember what size mine is but you can do this. Get a piece of string and route it around the pulleys...then measure how long it is. Take that length to autozone or whatever and tell them you need a belt this length with this many ribs.

On mine I removed the smog pump and A/C compressor but I retained the A/C style power sterring pump bracket, also my crank pulley is an underdrive. I run a 69.5" belt. If you have the stock crank pulley and the a/c still on Id guesstimate that youd need something around 75"-80". Make sure you route your belt correctly when you do this, its VERY easy to get your WP turning the wrong way.

although its easy to see the spin direction of the WP, if you happen to have a diagram, or can make one on paint for my reference it would be greatly apreciated

This is an odd thing. You're better off finding a piece of string & routing it, then checking it. My friend removed his smog & got the same size belt as me, but it ended up being 1.5 inches too short. Then again I also put a 3g alt on, so it could just be me...
