<span>I'm hoping someone has 2 OEM exhaust manifold studs in good condition for a '70 3500S. The thread pitch on each end is different; the end which screws into the manifold has a larger pitch. I sourced two new ones through NAPA, but found that the unthreaded
'collar' in the middle is machined such that it is impossible to tighten the stud into the manifold; i.e., with any sufficient torque when attaching the exhaust pipe to the lower half of the stud, results in the upper half spinning. [I was going to 'cheat'
by grinding off a corner of an additional nut and thread it onto the top of the stud sticking through on the manifold, but the curve/shape of the manifold on the side I need does not allow for this]</span></div>
