Thanks for the response rabbit....I let them change rear shocks and the swaybar endlink and they were going to replace the bushings...but I said no, I will obtain these aftermarket arms and install myself.
I am in Canada here so you have to realize everything is about double here as compared to you guys down south.
MOOG swaybar link was 73.00 bucks..each KY rear shock 93.00.
I had a 3yr, 60,000KM warranty I will check into that suggestion though and call GM and find out if they are covered.
