Trailing arm question
 

Recently my Left trailing arm snapped in half, i have recieved the new part but when removing the old one the arm-to-chassis bolt was stripped and not able to be used again. Do anyone know where i can order a new one to get shipped to my home?

You probably will have to go right to your local GM shop. and they should be able to help you and send the part right to your house

I checked out this place, but had no real idea what you needed, maybe you can a part # and then go to your local GM shop.

Are you talking about the bolt that goes into the bracket or the bolt that connects to the knuckle? The bracket bolts and arm to bracket bolts can be bought at GMpartsdirect.com, the bolt from the knuckle to the arm can be found there too.
