Uppers are 71-72 specific.
Lowers are 71-87.

You will need 71-72 outer tie rods.
Which won't bolt to your existing steering because they are the wrong diameter and opposite thread.
You'll need either:
All 71-72 steering parts.
Or conversion sleeves and move your original outer tie rods to the inner location.

Or best answer,... Throw your 71-72 spindles in the trash and buy 63-70 conversion spindles for $229.
No need to change anything.
