Isn't it fair to say the biggest problem with the early A v8 exhaust is the exhaust manifolds, themselves? If that's true, he might start looking for magnum exhaust manifolds and do the required mods to make them work. Drivers side is the pain, but I think it's workable in this car. Tight, but workable. That factory drivers side manifold that pinches down around the steering column is pretty bad from what I've heard. Full disclosure, that's what we have in our 65, but I'm seriously looking at the mag manifolds. I already have the pass side jeep grand cherokee one with the 2-1/8 opening...
