camber adjustment

i was wondering how i go about adjusting the camber on a 73 charger. i have negative camber on the passenger wheel. any help would be greatly appreciated thanks

On 73-74 B bodies the camber/caster is adjusted on the shaft mount. (It's on a slider)

It has to be done on a front end machine. Don't trust a new guy just outa tech school either. Check around for a shop thats been in business for awhile.
