1969 Dart Street/Strip (Re)Build
I did figure out why the calipers were leaking. Whoever put them together forgot a seal on each side and had the center plates installed/flipped wrong.
Notice the plates aren't flush with the caliper body

At the top, there are 2 seals required and only 1 seal required at the opposite end.
Seal in body
With spacer installed
Notice how flush the plates are to the body now
Hopefully that problem is now fixed.
