My feeling is Moog is always going to be best. With that being said, i did have a reproduction UCA for my 67 (I didn't end up using it) as I rebuilt both of my originals and became very familiar with them inside and out. There was nothing about the reproduction that made me think it would be inferior to the original. But my originals were 4-bolt upper ball joint rather than the 3 bolt as most are and I wanted to keep with that. I didn't want 3-bolt on one side and 4-bolt on the other.
