What I have is a 65 Dart with no torsion bars, (went to coilovers) a rack and pinion, and a modified steering column cut back to the firewall, with multiple joints so it can be routed differently to the steering rack. So I have room around the steering shaft where stock early A's don't. Will a cheap Summit 1 5/8 under chassis header fit as is, or with moving a pipe or two? I am guessing the drivers side will not be an issue, and for the passenger side the main problem would be getting by the inner fenderwell for the center tubes? Any info helpful. Does anyone know how far out the passenger side tubes are from the head on A body 67 up headers are?
