I am interested in obtaining part numbers for the Flangeless nut only.

This is part number SC866D.

I\'m looking for parts for an AutoBlock I. The online PDF for AutoBlock model I and II are labeld as AB III. Are parts labeled for ABIII applicable to AutoBlock I systems?

If they have the same part number they will be compatible. Items with a different part number are not compatible between different generations of the equipment.
