273 V8 to Slant 6 Swap: 1965 Dart

Slant 6 Z bars are a tad longer than the V8s. You'll need the early slant bell and flywheel (and thowout arm, I assume), and a set of early slant 6 motor mount brackets (the K frame is the same). You'll need a radiator too, as the slant has the bottom hose on the opposite side of the tank. Your accelerator cable should hook up to the late slant. Whoops- scratch that, you'll need a longer cable from a later slant. But your pedal linkage should work.
If the slant is from a truck, you'll need a pass car pan, pickup and dipstick/tube.
