YES 5.9 Magnum manifolds work in early A bodies. Here is exactly how!

Now this is a very cool idea. I like the look a lot better than than using an old 273 exhaust manifold on the driver side. How much clearance to the inner fenders do you have on each side?
Passenger side is very close especially since I shimmed up the driver side. There’s probably in one section about an eighth of an inch between the inner fender and the embossed numbers on the manifold. Driver side has plenty of clearance
