The man wants MORE caster. How about this idea?

The odd thing is, you should/can be able to swap spindle side to side without disturbing the UCA alignment cams and not remove the strut rods.
I had the calipers front mounted on my '70 Charger but wanted to run the rear mount and the later FMJ 2.75" single piston caliper so I swapped the knuckles side to side. Of course it all swapped and fit right and the alignment didn't change enough to feel it. It still drove and felt the same to me.
