Aftermarket Upper Control Arm Question

[vintageracer]

I just purchased a rust-free 1967 RS/SS 350 4 Speed Camaro from the original owners. Plan is to rebuild as a driver for my wife to replace her 1967 Corvette that burnt up in a garage fire in July 2020.

Given the original condition of the car mods will be kept to a minimum with any mod being directed to make the car more driveable and enjoyable. As such the short mod list includes Vintage Heat/AC, Holley Snyper on top the original engine and basic suspension.

Suspension mods will be limited to new bushings, sway bar, springs and potentially upper control arms.

I know the stock front Camaro sub-frame is full of suspension compromises which ultimately leads to my question:



Without changing the factory lower control arm since it's just along for the ride which QUALITY aftermarket upper control arm provides the BEST upgrade in upper ball joint location for more caster and a better street driving experience with the stock disc brake/ spindle and stock sub-frame?
