Thank you! It looks like the Power Steering pump belt goes on 1st, then the alternator belt, then the A/C belt. From the looks of it, it does not have an extra idler pulley next to the power steering pump. Thank you again, you've cleared things up!
I am wondering if the 1973 Mach 1 used a single groove water pump pulley or a double grove pulley? what is the part number for the double groove pulley? Can anyone provide a picture of there original 351C with A/C? The only reference I have is from Jim Osborne reproduction publication: 1969 Ford Products Engine Equipment Assembly Manual, they did not offer one for the 1973 model. On page 78 it seems to have a double groove pulley as well as an idler pulley to the left of the Power Steering pump. I would also need a picture and part# for that idler pulley, if someone can provide it. Don't know if in 1973 Ford decided to eliminate the idler pulley as well as the double groove water pump pulley. Any info would be much appreciated.
