I am not really sure on the numbers but what I did was I took a piece of rope and just wove it thru according to the directions thru the pulley system and then when we got that we marked on there were the belt would end and then measured it with some tape measure and found out that way.

Well you can't and I would not try. Go and get you an AC delete idler pulley. Its like 38 bucks and came on LE1s.

Then, take the airpump off, remove the vanes inside and put it back on. Now you still have the factory belt length and everything.

I used a pair of tin snips to fix the airpump.
