Fathertime,
Here`s a short on the history of teardrops !!
This is the pre-Teardrop lug Sonor used from 52-54. Unlike the MIJ copies, it has no flange around the bottom (toes) You do not need these, notice the fasteners are threaded into the lug caseing !! It has two washers, one flat and the other a locking, and a incert and spring !!
