I recommend Brillman company, they are in VA so it will get to you quick. I got a model 70 harness and it looks just like factory, except better because they solder all the lugs for permeance.

Double check this is the right part for your model.
From the pictures it looks like your tractors clutch and driveshaft cover is missing, puts the spinny bits dangerously close to the harness. if you cant find that cover for cheap I definitely recommend finding a wide enough piece of sheet aluminum and bending it to make a driveshaft cover.
