It is a custom built Fabco. The diff is from an Eaton HO111....from what I am told. I think it is an HO72, but have yet to track it down. The Outters are basically Dana 60 hub/ spindle. The knuckle is all fabco. Fabco # is FD20, They also made a heavier duty one, the FD30 with 5 inch wide brake shoes!!! They were originally made for an International Fire Truck. The PO put on the spring perches, & had them under a Toya PU.
