I've checked here for belt length info before with no luck on my particular combo. I thought I'd post my setup to maybe help someone else in the future. I've got an 88 5.0 HO from a Lincoln LSC. I removed the air pump and a/c compressor and bracket, installed the power steering pump brackets from a Mustang HO with no a/c (... the ones that move the power steering pump up higher). I then tried several belts and discovered a 75" fit perfectly (I had to remove the upper alternator bolt and loosen the lower alternator bolt). The belt routing is a little different than other Mustang stuff I've seen, it's similar to about a 93 F-150's. The belt routes from the bottom of the crank pulley, up and clockwise over the alternator, under the tensioner, clockwise over the power steering pulley, counter-clockwise over the water pump pulley, off the bottom of the w/p pulley and clockwise around the crank pulley. The 5.0 is in a 97 Ranger 2wd/swb, and the p/s pump is from the Ranger, all the other pulleys are stock. Hope it can help somebody.
