Assembling the front shoes doesn't require any tools. But every point of metal-to-metal contact is greased using the correct brake grease.
.
Note the stack order on the anchor pin (at the top): the winged retainer goes on first (on its step against the larger shoulder), then the rear shoe's retractor spring (whose other end holds the cable guide to the shoe) on the smallest step of the pin and the shoe on the larger shoulder (using the rear hold-down pin & spring to keep it in-place), then the front retractor spring & shoe (with its hold-down). Then hook the autoadjuster spring to the front shoe, hook the pawl on, then route the cable & hook it onto the anchor pin. After the autoadjuster is greased & assembled (fully-retracted), put it against the backing plate behind the shoes, put one end on a shoe, and spread the shoes enough to get the 2nd end on. Finally, measure the drum and spin the adjuster out to match.
The spindle bolt heads got cleaned when the seal shoulder was wire-wheeled.
I also dressed out the burr in the spindle threads, and swapped to the later bearing lock washers so auto hub locks can be installed.
