Never mind. I figured it out. I looked on again and realized that I was misreading the service manual’s description that was for sale. I picked up an original for $11.88 w/free shipping online.
FWIW to other searchers: I was looking for a Chrysler service manual by year specific to my model/serial number. Chrysler does not do this for the 7.5 hp. They have a 180 Sailor version and a 150 Sailor version–that’s it.
