Re: belt sizes
If you remove A/C, you can use the same size belt as it routes differently around the idler pulley. As for removing the PS pump, I'd leave that pulley in place and remove the guts of the pump. That pulley will act as a second idler and you can still use the current belt. If you must take the pulley off with the unit then you'll have to measure and take 1-2" of length off to account for tension the belt will need once its installed.
