I have a 2002 Blazer LS 4x4 and just purchased a new weld-on 2.5" cat because mine is bad. My question is what parts exactly do I need in order to get the job done? I know i need spring bolts but what size and how many? Can someone give me a detailed list like that of what all I will need please?

 

Shouldnt need anything else unless something breaks. Cut the old one out and weld in the new one.
