Yes, 2*, or 88* off 90. The repop perches must be relieved some where they fit the axle tube. I fixed one hack job on a 69 Camaro with the reproduction perches. Had the axle housing upside down with the leaf springs held in place with the front and rear diamentions secured with some wood strips to act as a guide.
I think the repop ones are good, but they lack some detail, like the stiffening indents on each side.
