OEM Upper Control Arm Bushing and Positive Caster

Finished replacing the loose bushings on both UCAs, used new moog rubber and added the collar/retainer, I managed to make out from a standard size pipe I found. They fit very tight, I think the metal pipe I found is the exact same size as the original metal collars I have on the rear UCA bushings.
For now, all holding in place.
I believe that setting the UCAs for maximum positive caster puts the UCA and bushings in a twisted position compared to the frame and cam bolts and that may cause premature failure.
The offset bushings would be great, but still, I'd not feel comfortable to set cam bolts for max + caster using those, just do not seem they will last long.
Curious what alignment others have on stock UCAs and bushings.
I am setting mine now for
Camber: - 0.7
Caster: + 1.5
All stock parts.
