Because these (now 50 year old cars) were not built to the tight tolerances of todays cars, I often stack both front / rear spacers on the UCA poly ends (both) only on the front. That shifts the ball joint receiver further rearward (more caster) without putting the UCA in a bind. On my personal Duster, I only did that procedure / fix on the drivers side. The Butch Leal street Duster has the passenger side off. Just the way they are.
my favorite part is the way the fenders droop over your tucked in front wheels/ tires......and of course the patina.....hard to duplicate that!
