Motor kit WE17X10010 wiring into old gas dryer

Any one know how to wire this “Universal” motor kit into a 30+ year old dryer?
Father in law purchased and ask me to install because he couldnt figure it out.
He is an retired Building engineer, I myself am an ex-Hobart Commercial Kitchen Service
Technician, and neither one of us can figure it out, any help is greatly appreciated.

Motor kit: WE17X10010
Hotpoint Gas Dryer model: DLL1550AALAD

Did it come with instructions?

I found this on the internet. How many wires does the old motor have?

I also found this.
