I am new to this group. I have a Passport (1981) and the exhaust assembly is loose from the cylinder head. One stud is broken off in the head. I will have to tap with out, I guess. I am wanting to know what parts (gaskets) belong between the head and the flange. Also, I imagine there are nuts for the studs that secure the fange. Would any one know the size of these nuts? I am wondering if, after tapping out the broken stud, I will be able to use a stock size stud (I believe I saw these offered from one of the online parts stores) and, again, what size the nuts would be. Also, does anyone have an opinion as to whether the Hayes c-50 c70 c90 book is worth the $36 dollar cost. Thanks, Jeff
