bolts!

Today i decided to take of my dp alon with the main cat. now i have a small problem, i wont to use the old bolts that were on rear of the main cat so that i can use them for my new dp. I could not take them off so i decided to go to homie depot and find a bolt that would fit the nuts i just took off. I got close but none of them did a perfect fit. The closest one was i think a 1/2 i think. should i use this new bolt and buy a new nut? or should i get some pliers and try to take off the bolts? :screwy:

you know its metric right? anyways, if i were you i would just get new ones. :2cents:

Get new SS bolts and new gaskets. Old ones jsut mean rust and exhaust leaks.
