So, while trying to replace old worn gaskets between my exhaust pipe flanges and the outtake on my EA81 (1983 BRAT) everything went fine except for one post won't tighten all the way anymore. I cut out new gaskets on my own, but because of that one post that won't tighten, I don't have a good seal (the car's way loud now ha ha). Are the threads in this hole on the bracket or are they on the actual engine block? (do these holes even go all the way into the engine block and not just the bracket?)
I need to know so that I can decide whether it's better to buy the brackets off of somebody or to just do a helicoil and rethread the hole. What do you guys think?
