SPC adjustable upper control arms

HemiDenny said

HDK sells small ball-joint pre 72 adjustable chromoly UCA assemblies.........$298 plus shipping. They came standard with street friendly adjustable poly-ends but you can upgrade to heims (non street / drag pack ) for an additional $50.

Presently, they are not shown separately, just with the coil over only package

These look really nice and the price is great so I would consider getting them instead.
My only question is should the piece that holds the ball joint not be at an angle? It is at an angle on the original arms as well as Hotchkis and a few others to compensate for the overall arm being slanted backward in the car. Then there are other aftermarket arms that are just like these HDK ones as well.
