72 Cheyenne K20 : "a replacement for my Free/Lock hub knob "
If you have a stock Spicer hubs with the blue plastic insert it's rare... like chicken teeth rare!
Here is my 2cents,
FRONT:Consider upgrading to the Warn premium all metal hubs,
Warn part#9072 (the same # for all '67-72 D-44 front axles)
Cost between $60-120 for hubs,
might also need a spindle nut kit.
REAR: Many choices out there, depends on how you use you truck. The Eaton rears are strong, sometimes hard to find new parts for them (depends on where you live). Could you add to your posting? How you use your truck/what kind of driving you do?
