To increase the caster by 3 °, you have to move the upper ball joint back by about 13 mm (approximately because I don't have the courage to go to my garage to precisely measure the distance between the two ball joints), which will move the wheel * / - 6.5 mm in the wheel arch; I don't think that's really a big problem.
I read I don't remember where that the European Pantera had more roulette and that Ford asked that there be less on the US models because in the 1970s, unlike the Europeans, you Americans were already very accustomed to power steering, therefore light, on the one hand and were already subject to speed limits on motorways which made great stability at high speed unnecessary on the other hand.
