Reading is fundamental. I did not address "converted" cars, did I? OP is asking about a '68. At some point Mopar did eliminate the LH threads, but not on a '68 car.

Screw off. YOU did not say "68" you said "all cars." ALL That is what you said. k?

Here is what you said. As you yourself said, "reading is fundamental"

7/16" studs on the 4" BC, 1/2" studs on the 4.50" BC. All cars came with LH and RH studs/nuts regardless of stud size or bolt circle.
