Please help to identify these drop spindles - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Well, I did something I said I'd never do, buy someone else's project. But I fell in love with this sweet 1963 GMC 1000 truck. The PO did most of the suspension work, air all around, and drop spindles up front, it'll lay the frame currently. I'm trying to get some things identified for replacement ball joints, swapping over to some 6 lug rotors, and steering needs, but cannot identify these drop spindles.

The spindles appear to be 2-3" drop spindles
Both have "SFA" cast into them
the Driver side has GM87L
the Passenger side has GM87R

The rotor on the spindle has several things cast into it;
Min thick 1.215
K22
3968998 (I think)

Do these look familiar to anyone? I'm guessing that the "GM87" cast into the spindle may mean that it takes the 73-87 ball joints and steering?
