okay Im going to replace my cat this week I got the new one already but I need to know the bolt size i will need...mine is a 98 and has the 2 flanges in front and behind the cat. my rear cat flange bolts were replaced recently but not by me so Im not sure the correct size because on the stock cat, it has the bolts pressed into the cat front flange that connects to the y pipe.


any help is appreciated

thanks

Jeremy
