The Long Island Catalog lists 2 upper control arm shafts for 66. A square cross section for 66E and a round cross section for 66L. I have one of each on my Feb 66.
I do not plan on getting my car judged but since I am planning on a front suspension rebuild I was curious when the change was made from square to round.
