Broken auger and housing

Repairs were simplified by watching the on-line video. Only problem was the screw on collar on the end of the auger was broken and the only way I could buy it was to purchase the entire unit for @129.00. If it was available with the entire unit why couldn't I buy it by itself? I wound up drilling out the end of the collar and putting a small screw and washer in it to hold the D ring in place. Working great so far.
