I looked at info 7.4 litre engine. There is a diagram for belt routing for no ac. Probably need shorter belt. No ac pulley or idler pulley in the diagram.

Actually, we figured it out. Sorry I didn't include engine size, which is 5.7 and what we ended up having to do was remove compressor, replace with ac bypass pulley and use same belt. Thanks for your research, though.
