Michael,
The minimum parts required are:
1. Spindle or swivel axle, as it has the caliper attachment bolt
holes that the BE spindle doesn't have.
2. Kingpin, as it is a different diameter to fit the spindle
3. The caliper and all its attachments
4. Hub and brake rotor.
But, this gives you an opportunity to use the best a-frame and lower
trunion pin between the early and late. The A-frame might or will
have provision for a sway bar that you might want. You might want to
use the newer springs if your BE ones are fading. Given the
difficulties associated with removing the lower trunion pin, the most
expeditious method is often to just swap out the Aframe with kingpin
and spindle attached. There is less disassembly involved. You don't
even need to remove the hubs or anything. Do check for play in wheel
bearings first, and also in the king pin and trunion. Leave the
steering arms attached to the spindle, and undo the connection at the
tierod end. You also need to move the steel brake line a little.
