just as it says. i've finally got my plugs/wires changed on my 97Z. and on that note, i recommend never doing plugs/wires unless you're installing headers at the same time!!!
i need to know which size of a stud i need to go pick up to put in my ypipe to manifold flange. yes, i snapped one off....go ahead point and laugh at me!!!
i'd appreciate any help so i can run to town and get the stud and assemble my car.
thanks,
Michael.

 

10220453 is the part # for stock exhaust stud to y-pipe.. I dont know the size.....
