1983 manifold to downpipe stud sizing

I need to know the thread pitch, diameter of the stud, and overall length of the stud as i stripped the threads on mine after installing new gaskets. I searched but couldn't find a definitive answer. The stud is into the end of the manifold, where the down pipe attaches, leading to the first precat. I've included a picture so there isn't any confusion. Sorry if this is a repost, like I said I searched a good lick and came up dry. thanks!
