1966 Dirty Dart

Keep things simple. Did it have a shifter when you got it? Most likely you can use the stock shifter. Does it still have the original fuel line in good shape? If so, re-use it.
I re-used some of the original fuel line and I flushed it out real good. I had to cut some of it to attach a electric fuel pump near the tank. I lost some of the column shifter parts so I went ahead and installed a Hurst Shifter on the floor. I found the missing pieces later in a box I had stashed away so I wouldn't lose them haha.
