Hi Tim,
Yes it wasn't a big problem and pages (15-10-1 and 10-10-12) from the manual were of great help. As you mentioned the mechanic installed it via wrong course resulting hard steering. I went under the car and helped according to picture. length is 2480mm and I used Ford crown Victoria belt item number F5TE 8620 FA which is exactly same. There is a very helpful parts portal which gives you alternate parts (part interchange) which might fit ..... it is https://www.autopartskart.com/
Thanks again
