I also fought to get the crazy ass MEL exhaust manifolds that bolt in two different directions with brass nuts on studs that stay in the upper part of the manifold and bolts that hide underneath and may hold back oil? One nut had to be chiseled off as it was stuck and rounded itself off. Another nut was misshapen from heat and/or overtightening? That required some metric help to be removed. I held up the fender well headers and they should fit pretty well once my flanges come in and that spaces them out another inch or two. I will need to trim the inner fender well opening up higher as well. Also they leave ample room for steering shaft to live!!!!
