Updated SPITFIRE HEADER INSTALL 63-66 A-body

As far as Durango/Dakota manifolds go, I ordered a set of Dorman replacement manifolds from Summit Racing and they do not fit. Passenger side manifold is too thick/wide and hits inner fender as well as the drivers side hanging up on the steering coupler. Also the dump on both sides is at a bad angle. They could be made to fit, but I felt it was more work than it's worth. I'm now in the process of modifying Summit brand Durango/Dakota headers to fit. A bit of work but it is gonna be a better fit and I won't have to use dual exhaust like the TTI setup.
