Question: Not enough Caster adjustment in my big block Duster.

Any chance you have another choice for an alignment shop? A tech that knows what they're doing should be able to make it drive decent, even if enough caster can't be achieved with adjustments.

Moog makes offset upper bushings to provide add'l caster if that's the issue. Part # K7103

Sorry, but too much caster will cause the car to wander and no amount of toe or camber adjustments will stop it. Think of it as a motorcycle. The front fork has a slight (or serious) rake to it. This allows it to track more easily. If the front fork was straight up and down, it would track terribly. You would have a hard time keeping it straight while driving. If there isn't a kit made (and it sounds as if there is) you can usually make a shim fairly easily, sometimes from a washer if it is shim style. If it uses eccentrics, you will have to find something that will work. A little ingenuity goes a long way!
