I have replaced the headers on one of my Ks, it was the cause of some of the noises I previously reported on here. It has a crack just before the section where it joins the rear can.
Some posters have said it can be welded, others say not. Either way it is available for any who would like a spare set and would be willing to weld the small crack.
I post this anticipating it may spark some debate, my interest is in clearing some space, let me know if there’s any interest.
