the alternative to the delete pulley, is to switch an idler pulley to a grooved pulley and use the belt i believe from the 3.8. i posted it a while back somewhere on this forum. ill see if i can find the info again.
UPDATE: here is it http://www.moddedmustangs.com/forums...ac-delete.html
70.5 inch belt, and a grooved idler pulley from a v6 swapped into your tensioner. dont know if this will be any more cost effective that running a pully where your compressor was.
