1972 Daddy Daughter Duster
Got the adapter brackets mounted onto the drum spindles. Other than drilling out a threaded bolt hole to 1/2 inch (pointing to in in pic 1) and using a floor jack to load the suspension in order to line up the holes for the steering linkage, no fuss no muss.
Drill out this hole with 1/2" bit
Use floor jack to line up holes for steering linkage
Studs in hubs
Used the rim to hold the hubs in place so I could get the 70lbs torque required.
